Description of the activity- For all VME systems, replace the RIO3 modules (LynxOS) by the MEN-A20 modules (Linux).
The latter are supplied by BE/CO- The VHDL firmware of the VME boards needs to be adapted to the MEN-A20- The FESA class has to be adapted- The VME systems crates are
- BIC installed around the LHC ring, in the Injection and Extraction regions and in the SPS ring (~40 front-ends have to be upgraded)
- SMP controllers installed in the CCR (2 front-ends)

Why during LS1?- LynxOS power PC are no longer supported by BE/CO
Risks / impact if not during LS1- Not enough spare to replace faulty RIO3 modules in operation- No support if any malfunction → Loss of monitoring
Time period- Before August 2013- 2 weeks for installation (4 CPU / day)
Manpower- Stéphane to replace the modules in the alcoves and check if the monitoring works- Contribution of MS section to adapt the FESA class
Contributions from the other groups- The MEN-A20 boards are provided by BE/CO group.
Potential showstoppers- Delay for supplying the MEN-A20 from BE/CO

- The prototype module will be installed on spare fibers (1 or 2)- Several configurations can be implemented for monitoring (Raspberry PC, Python
interface…)
Why during LS1?- Some fibers optic show an important attenuation of optical budget since their installation
Risks / impact if not during LS1- Beam permit not correctly transmitted on the BIS loops → False Beam Dump
Time period- Before August 2013- 1 day for the installation
Manpower- Jonathan and Spyros (and MS?)
Contributions from the other groups- None
Potential showstoppers- None
2 – BIS : Install fiber optic monitoring for the Beam Permit Loops (#11124)
4
Description of the activity- Monitor the optical signals, and anticipate false dumps due to a decreasing of the optical
budget

Description of the activity- Upgrading of the CIBF units. They are mainly used for the SPS Extraction / LHC Injection
User Permits (Experiments and LBDS links). In total 38 pairs of CIBF are in operation- At least the CIBT board (used for monitor and test the CIBF) needs an upgrade.
Why during LS1?- Lack of monitoring- Not possible to remotely measure the optical power- Obsolescence of the components
Risks / impact if not during LS1- Diagnostics issues → Loss of availability- CIBF spare limited (due to obsolescence)
Time period- Before Feb 2014
Manpower- Stéphane- Contribution of MS (FESA and Java GUI follow-up)

Contributions from the other groups- None
Potential showstoppers- Depending on the design study, there will be
more impact on existing cards → Design a new CIBT and potentially a new CIBM

Description of the activity- 3 BICs and about 25 CIBU links have to be installed and commissioned.
Why during LS1?- The installation has to follow the Linac4 schedule
Risks / impact if not during LS1- Stop the progress of Linac4 project
Time period- Before August 2013
Manpower- Christophe, Stéphane and Nicolas- MS: Instantiate FESA and BIS GUI for new FECs
Contributions from the other groups- All L4 equipment systems connected to the BIS
Potential showstoppers- The Linac4 planning
4 – BIS : Deploy a BIS for Linac4 (#11123)

Description of the activity- A Beam Interlock Controller needs to be moved from UJ56 to USC55
Why during LS1?- Radiation issue
Risks / impact if not during LS1- R2E problems after LS1
Time period- Before August 2013- Few days
Manpower- Christophe and Nicolas
Contributions from the other groups- EN/EL to install fibers in USC55
Potential showstoppers- None

Description of the activity- If a change has been made during LS1 on the users side, the concerned connection with the
BIS must be re-commissioned.
Why during LS1?- The commissioning has to be done before the machines restart
Risks / impact if not during LS1- Problem receiving user permits → Problem for Machine Protection
Time period- Before August 2014
Manpower- Christophe and Spyros
Contributions from the other groups- All equipment systems who will make changes
Potential showstoppers- Late information about the modification of a user system- It implies the participation of people from each user system
6 – BIS : Re-commission CIBU users who will make change during LS1 (#11126)

Description of the activity- Individual System Test for the BIS and SMP system prior to beam operation- It regroups pre-operational checks and automatic CIBU tests
Why during LS1?- The tests have to be defined and performed before the machines restart
Risks / impact if not during LS1- Malfunction of BIS or SMP (with all the consequences)
Time period- Before August 2014
Manpower- Stéphane and Christophe- Review and transmit specs to MS
Contributions from the other groups- None
Potential showstoppers- BIS new hardware / new VHDL / new FESA class…

Description of the activity- Connect the LHC BIS to the LBDS re-triggering system (so called 3rd channel).- This channel is directly connected to the LBDS to provoke asynchronous dump in case the
TSU doesn’t trigger the expected synchronous beam dump- It implies a new CIBG card (Beam Permit Loop Generator)- The CIBG 3rd channel should reach a high availability level
Why during LS1?- It has to be done for the restart of the LHC
Risks / impact if not during LS1- Beam potentially not dumped → Pb for Machine Protection
Time period- Before August 2014
Manpower- Stéphane- MS: Follow-up for FESA, Java GUI and PM data integration
Collaboration for the other groups- TE-ABT
Potential showstoppers- None
8 – BIS Collaboration : LBDS improvement (#12054)

Description of the activity- Specify the functionalities and hardware for the BIS version2- It will be developed between LS1 and LS2, and installed during LS2

Risks / impact if not during LS1- Delay on the BIS2 project
Time period- none
Manpower- Stéphane
Contributions from the other groups- None
Potential showstoppers- None
