DAQ Status for cosmic-ray test in RAL

1. DAQ Status for cosmic-ray test in RAL • Contents • Status • Setup for cosmic-ray test bench • Schedule Hideyuki Sakamoto MICE Phone meeting 12th July 2007

2. Scheme for DAQ • DATE (Data Acquisition and Test Environment) framework. • Need to build modified readout program for MICE in DATE. • Other part (e.g. data format, eventBuilding) will use default one. • Readout program is prepared for each modules. • VLSB module made by FNAL • TDC/ADC module made by CAEN • Sub-framework (readout+initializing) is under preparing by James.

3. Status • New RHB is coming today, taking data with test charge injection/cosmic-ray. • Threshold: 100,120,160,200,240 • Bias ON & Heater ON • Try heater current to be low by heating cryostat with OXFORD temperature controller. • Started working on DATE from last week. • Yesterday, once success to starting readout program in DATE. …fail at 2nd try… • Should be finished in next week at RAL. • Readout code is under implementing. • Sub-framework is almost done? • Command lists are replaced from AFEII to AFEIIt. • Can be tested at stand alone. • Linux driver for SBS(bit3) dataBLIZZARD to test in Imperial. • In next week, test will also be done in RAL.. (using CAEN)

4. It seems LHB  RHB compared with previous version for Excel sheet. Threshold 100

5. Threshold 120 Increase noise

6. Threshold 160 Increase noise

7. Threshold 200 Decrease noise

8. Threshold 240 Decrease/Same? noise

9. OLD version (afeIIt_vlsb_daq_810.c.xls) Previous RHB Bias ON － threshold 160 －w/o charge injection test_pulse_033_old-excel_thre160_heater_on_bias_on

10. OLD version (afeIIt_vlsb_daq_810.c.xls) Previous RHB Bias ON － threshold 200 －w/o charge injection test_pulse_032_old-excel_thre200_heater_on_bias_on

11. OLD version (afeIIt_vlsb_daq_810.c.xls) Previous RHB Bias ON － threshold 240 －w/o charge injection test_pulse_031_old-excel_thre240_heater_on_bias_on

12. Comment for today’s result • Noise rate seems to be reproduced as previous RHB. • Noise rate seems to be reversed at threshold 160 by eye. • This may not true. • For treatment of heater current, it is better to compare with the same RHB, so taking data with default setting with this new RHB.

13. Possible reason for RHB noise • Remember that we do not see ANY noise with test charge injection data. • Let’s check this fact by taking data as changing triggering rate. • This will be done by LED pulse injection. • If we take data with high rate, we cannot not see any noise as LED data. • It not, there is problem at the setting of self trigger mode. • Our goal is to identify/remove the noise. • If heater current is the reason, then we should see any changeable results from it. • We should check it by taking data with the default setting as previous.

15. Slow progress for DATE Yesterday, reach to goal, but 2nd try was failed….=> finish in next week at RAL! Last week Goal in RAL? Yesterday

16. VLSB data format for new firmware (ver. “ce”) Old Version “cc” New Version “ce” Header First 4/5 lines (variable) 7 dummy lines (fix?) + Trigger location (line#8&9) + Discriminator hit map (line#10-17) Body Channel address/ADC(128) Channel address/ADC(128) Footer 2/3 lines 0 line? TOTAL 135 145 • 10 lines are added for debug information. “ce” is soon available. • -- Need to check header length to kwame -- 32-bit VLSB data ADC ADC Counter Status bit ３２ ３１ ３０ ２９ ２８ ２７ ２６ ２５ ２４ ２３ ２２ ２１ ２０ １９ １８ １７ １６ １５ １４ １３ １２ １１ １０ ９ ８ ７ ６ ５ ４ ３ ２ １

17. Check numbers for cosmic-ray test To readout 5 stations…. • 2 VME crates • Slow control will be separated from DAQ crate. • 8 AFEIIt boards • To readout 5 stations, we need 3200 channels in total. • 8 VLSB modules • 1 VLSB is needed to readout 1 AFE board • 1 ADC & TDC module • Used for readout defining counter

18. How many channels are used? Upside Define counter 2channles for TDC/ADC Patch panel Light shield box embedded 5 stations 3200(640 x5) channels for VLSB Low energy filter block Downside Define counter 2channles for TDC/ADC Requires 4 for TDC/ADC & 3200 for VLSB

19. How about VLSB modules? This cabling is virtual. #5 #2 #1 #4 #3 8 AFEIIt boards = 8 VLSB modules

20. V2718 MIL 1553 Setup for test bench (R12) Slow control/Monitoring VME crate Optical cable DAQ(LDC/GDC) VME crate Optical cable VLSB VLSB V2718 VLSB VLSB VLSB VLSB VLSB VLSB V1724 V1270 V977

21. Schedule • This week (~13th) • Checking signals for newly RHB today! • Testing code for VLSB module in Imeprial. • Waiting for driver for SBS(Bit3) dataBLIZZARD. • Implement readout code for new firmware (ce). • Next week (16th ~ 20th) • Set up test bench at R12 in RAL with JSG/Mike/Nicholls/Craig/etc. • Clone system for Geneva University • Testing code for CAEN modules(V977, V1270, V1724) in RAL. • To test VLSB modules in RAL, need more modules! Please send to RAL! • Imperial’s VLSB will be in use for QA. • The week after next (23rd ~ 27th) • DAQ workshop (23,24,25) • Finish to setup DAQ system (mainly to debug readout program, I think)

22. Here coming 2 cryostats & 1 compressor & 1 transformer & 8 AFE boards & 5 stations & 25 inter/external waveguides & 1 patch panel & 2 VME crates & 2 NIM crates & VME/NIM modules & 2 DAQ PCs & other stuff… R12
