Magnet environment 1

Availability of LHe when the magnet is shipped cold 1

Ferromagnetic objects in close proximity to the magnet adverselyaffect the field homogeneity of the magnet.

Just like the Impact magnet, the OR 35 magnet is usually shipped cold. No time will be lost to precooling the magnet. Instead it can be filled with helium immediately after it has been moved into the building. For that purpose you should have at least 450 liters of liquid helium on-site.

Refer to chapter 3 in this register for checking the temperature and/or the liq-uid helium level of the magnet.

In case the magnet is shipped warm, refer to chapter 3 in Register 1 of the Start-up manual.

1 - 6 GeneralIssuing orders and transport procedures 1 All transport activities, including delivery into the RF room, should be performed by a licensed carrier

only. Transport of the magnet or any other heavy components by SIEMENS employees is prohibited.

Transport routes 1 Before issuing orders to the carrier, the project manager and the architect/construction engineer must

determine the weight capacity of the floor along the transport route and in the temporary storage areas. The architect/construction engineer must certify in writing that the route can withstand the expected load.

It is the responsibility of the carrier to obtain information concerning the various transport routes before the actual transport. Copies of the transport plans and certification must be provided by the carrier upon receipt of the order.

Issuing the order 1 The order for transport by a licensed carrier must be issued in writing. In addition to general

information (e.g., a list of parts, etc.), the order must contain the following data and documen-tation:

Copies of plans for the transport route/temporary storage areas. Copy of the certification regarding the weight capacity of the floor. Final destination of transport.

(It is recommended that the carrier obtain information concerning the transport route before the actual transport).

Weight of components to be transported (refer to Register 1 of this folder). Dimensions of components to be transported (refer to Register 1 of this folder). Use of transport devices.

Installation of the RF-room 2Siemens AG Register 8 M2-050.031.01 Page 1 of 2Medical Engineering Rev. 09 04/99 TD SD 23 Plan

Read this first 2Most of the modular RF-rooms used in Germany and Europe are manufactured by Siemens Matsush-ita GmbH & Co. KG in Heidenheim and installed by a team of Simon Hegele employees. In view of Sie-mens Med minimal involvement in these areas and the separate, detailed documentation available on the subject, we are only providing General Notes for the RF-room installation.

However, you can always contact Siemens Med, TD MR 7, in Erlangen, if you have questions regard-ing the installation of the RF-room. The telephone numbers to call are ..-9131-84-3791 or 6201.

Safety 2The following should be worn during the installation of the RF-room: Protective gloves (made from leather) Safety shoes Safety helmet Safety glasses

When using other RF-rooms (e.g. copper or aluminium-clad RF-rooms, etc.) outside of Germany or Europe, manufacturers specifications and installation instructions should be used.

Refer also to Register 2 of this manual.

NOTICE

NOTICE

2 - 2 Installation of the RF-roomGeneral Notes 2 The RF-room and floor have to be completed before the magnet arrives at the site. Ensure that the

opening in the RF-room wall allows for easy transportation of the magnet into the room. The floor has to be level (including the grouting, etc.) It is recommended to start the installation of the first side panel at the corner located opposite the RF-

room door. The contact surfaces of the RF-gaskets (used with particular designs) should be free of grease. The nuts should be tightened with the torque specified by the manufacturer. The RF-integrity of the RF-room must be measured (attenuation 90 dB). The door contacts cannot be damaged. The protocols must be filled out and filed with the other protocols (register 9 of the system manual).

The spectroscopy retrofit requires a second filter plate which includes the RF wave guides for the gradient cables.Depending on the location of the second filter plate, the gradient cables may not be long enough. For this reason install the second filter plate in a way, which allows you to reuse the gradient cables.

Dont forget the RF-gaskets while installing the filter plate for the copper-clad or steel-clad RF-room.

Installation Prerequisites 3

Transport Requirements 3 Ensure that the magnet room is ready and the RF-shielding is installed. Ensure that the opening to the RF-room is large enough (refer to the Planning Guide). Verify dimensions of the RF-room opening (height, width; refer to the Planning Guide). Provide temporary storage for the magnet with sufficient floor load capacity

(refer to the Planning Guide). Ensure sufficient space for magnet installation (refer to the Planning Guide). Take into account obstructions due to dropped ceilings, support beams, and columns. Determine the final magnet location in the RF-room (refer to the Planning Guide). Verify that the water for the ACCU has been routed to the final location of the ACCU. In this way you

will be able to quickly connect the compressor. This is an important advantage when the magnet has been shipped cold, and the cold head has to be connected immediately to reduce the boil-off rate.

Rope off the unloading zone to prevent injury to onlookers. Avoid blocking emergency or other vital access routes to the hospital. Stay within traffic regulations. If necessary, get in touch with the hospital administration. Only a licensed carrier should transport the magnet to the site and into the magnet room.

To ensure maximum safety for the personnel and the system, the chains, straps, or other lifting devices, as well as the hydraulic lifts and the steel roll-ers must be in good working condition.

Read through this chapter carefully. It lists all the items/steps that should have been completed or prepared before the magnet arrives at the site.

The distance of the truck to the unloading zone determines the size and capacity of the crane.

Unloading and positioning the magnet 3 - 23Procedure 3

Check that the shut-off valve at the quench valve is in the closed position (handle is at right angles to the valve axis.)

Remove the VW25KF blank from the end of the shut-off valve and connect the valve to the site venting.

Ensure that the pipes used are supported and not left to hang on the connections alone. If the site venting is not installed, run the pipes to atmosphere outside the MR suite.

To minimize the amount of helium lost, open the shut-off valve slowly to approximately 15 degrees from the closed position and monitor the pressure gauge.

Helium gas should now be heard escaping. The vent line will cool in a few minutes until it becomes very cold.

When the pressure indicated on the gauge has dropped to 5 psi, the valve opening should be gradually increased until fully open.

Open the depressurization valve.

Allow the system to depressurize until the vent line has thawed, indicating the system is now at atmospheric pressure.

Remove the bursting disk assembly from the end of the quench valve and connect the site venting to the quench valve.

Remove the 30 psia valve assembly and replace it with the stopper rod (baffle assembly) which is packed in the accessories case.

Replace the 2 bar pressure gauge with the 1/3 psi gauge which is packed in the accessories case.

This procedure should be performed only by trained personnel, wearing pro-tective clothing.

Helium gas should not be allowed to vent into the MR suite or any other closed room.

Do not come in contact with cold components. Do not smoke or use open flames.

The following operations should be performed quickly to prevent air from entering the system.

Remove the blanking plug (A) from the end of the depressurisation line. There may be a small release of gas, but there should not be a continuous flow. If there is, cap off the tube and call the Oxford Service Department, since there may be a fault with the quench valve. Do not proceed further since this might allow air to enter the system.

Assuming there is no flow refit blank (A) and remove the large blanking flange (B) from the end of the quench valve and connect the site venting to the quench valve.

Open the depressurisation valve (C).

Allow the system to depressurise until the depressurisation line has thawed, indicating that the system is now at atmospheric pressure.

Remove the 13 psig valve (F) assembly and and replace it with the current lead baffle assembly which is packed in the accessories case.

Remove the 16 psia valve (D) from the 1/3 psig valve (E), remove blank (A) from the Tee, connect the Tee to the 1/3 psig valve and close the depressurisation valve (C). The system will now pressurise to its normal operating pressure, 1/3 psi.

Pack the remove parts and return them to the Oxford Service Department for re-use.(Address for the return parts on page 24)

Proceed with care during the depressurization procedure described on this page.

This procedure should only be carried out by trained personnel, wearing pro-tective clothing.Ensure DCL Baffle is on hand prior to carrying out this procedure.

Helium gas should not be allowed to vent into the imaging suite or any closed room.

Do not touch the cold parts. Smoking and naked lights are forbidden.

3 - 26 Unloading and positioning the magnetDetermining the temperature 3

General 3The magnet is usually shipped cold. However, the magnet may warm when it is shipped to certain countries or when it is in transport or storage for an extended period of time.For that reason, the temperature of the helium vessel should be determined as quickly as possible after the magnet arrives at the customer site. The temperature of the helium vessel is measured via the three carbon temperature sensors in the helium vessel.If the magnet is still cold, that is, the vessel contains liquid helium, the temperature can be maintained if you refill the magnet immediately with liquid helium. You will not only save time, you will also save a great deal of money.However, should the magnet have warmed, you have to pump down the vacuum and fill it with helium again.Refer to the next page for instructions on how to measure the temperature as well as on how to deter-mine the threshold between a warm and a cold magnet.

Component installation in the RF-room 4 - 17Installation of the filter plate 4To provide the service engineer with enough room, the RF filter plate together with the RFCC should not be installed in the immediate vicinity of the magnet. In addition, a more cost-effective cover can be selected for the RFCC.In a modular RF-room, the filter plate can be installed directly in the recess provided for that purpose. In a conventional RF-room the filter plate can be installed directly as well, as long as the RF integrity is maintained. However, we recommend the use of a filter frame (refer to chapter 3 Components in Reg-ister 1 and to chapter 1 'RF-shielding' in Register 4 of this manual). Install the RF filter plate (56 screws M10).
