2. Hardware Gas leak to repair in Station 4
HV discharge in Station 4 to be understood
SBC
Move to local accounts (AFS is not stable enough)
COVER
Make safer the masking of the channels
Check the multi-hit and FIFO full flags
SRB
Fix the NIM outputs (patch to be applied on all boards)
Heat sinks installation
Trigger matching

(Boards dismounted, patching will start the 8th of April)

4. Hardware II One DATA cable to be changed in Station 1
Installation of the shielding for the cable trays (Reminder: the data cables are RJ45 but the signals are LVDS)
Gain monitor module
Full development setup in 154 (16 covers,1 or 2 SRB(s) and a complete MPOD system)
16ch ISEG HV module repairing
Temperature sensors to be installed on the manifolds

6. Run Control Init procedure:
Recognize PLLs problems + automatic actions ( => restart ALL the PLLs )
Recognize links problems + automatic actions
Add masking of not connected straws
Add reset of internal links
SOB/EOB
Automatic checks + actions:
Masks
Connection to COVERs
Thresholds
PLLs
Noise spikes (induced)
Automatic reload of COVER parameters in case of reset
Readout of the HW configuration

8. VME Monitoring Produce the FW to access the data via VME
Generate histograms and optimization of the histograms update
Add the 25ns structure of the time distribution

10. Raw Data Analysis
Toy Montecarlo to estimate the data throughput in case of trigger matching, with various trigger rates.
Exercise the trigger algorithm(s)
Generate a root tree from the raw data (Straw only)
Data merging
Searching for problems in COVERs connectivity
Multi-hit and FULL full flags
Noise spikes
