Technology Department ELENA Fast Deflector : elements production and testing

ELEMENT STATUS DONE TO BE DONE DUE

Generator Box OngoingCabled, TBT by end november

Base plate mounted with HV switches, capacitors, resistors and relays. HV Cables with SHV-20

New Pickups, Controller board mounted (TBT)

End of November

Mid DecemberWith new pickups

PXI Controller Components to be ordered Software mainly done by JS

Jan did already most of the control and LabView implementation

Validation, testing…HVPS control to be testedFront-end computer architecture TBD

February 2016

Cabling from platform to generators

Ongoing Cables pulled by EN-EL and connectors on the control side mounted

Connectors on generator side to be mounted.

Mid February 2016

Generator Controller

Ongoing - EIS interface done (TBT)- Analog Receiver done (TBT)- Caen HVPS tested

- Power Control Unit -> finish schematic and routing, - Control crate cabling- Three crates to be assembled

Mid January 2016

Power Distribution Controller

Nothing done (AA)

March 2016

PXI interface Ongoing Based on existing design (HG)

Cabling to be defined. February 2016

Comissioning with beam scheduled for July 2016

Technology Department

ELENA Fast Deflector : safety concerns and commisionning

- EIS- Prepare safety documentation - Define tests to be done (lab and on-site)- Define clearly which and how much fast deflectors to be

connected to EIS- Safety discharge switches tested (Ross relays)- Prepare interlocks test procedure

- Correct reaction of the system to every interlockEIS Interface card

Based on BE-PO design

- Commisionning / Installation- Prepare commisionning plan and strategy- Installation should be ready by April-May 2016 for the two

ELENA ring extractions- Beam comissioning expected for July 2016

- Transfer lines fast deflectors planed for 2017

Technology Department ELENA Fast Deflector : high voltage pickups

There is still work to be done to get a precise high voltage pickup as requested for this application to avoid oscillations. (flattop and platbottom stability at 0.1%)A new pickup design has been already designed, on the base of the North Star high voltage probe, including a 50 Ohms series resistor to adapt to the cable impedance, reorganization of the components in «star topology», ground plane on low voltage side, removed adjustable capacitor.
