CSC commissioningBefore Christmas break• Turned on and checked communication with TMB, DMB, ALCT, and
CFEB for 6 peripheral crates (180o in ) on station 1: VME+1/[4-9]… • Problems (representative of those which will be seen by “Team-A”):
• PROM ID readback 0 and F on two CFEBs likely skew-clear cable problems
• One DMB reading back all zero’s likely firmware reloading• One LVMB temperature readback problem• All ME1/3 and ME1/1 ALCTs read 0 from on-board ADC +5.5V_B
line (N.B. values were OK as read by LVMB)• Found/fixed one set of swapped crate controller fibers at GBit
switch in counting house (VME+1/67)• Found/fixed one crate controller rx/tx swap
• Otherwise: successful communication with all components with final fibers, patch panels, cabling, cooling, LV power...

CSC commissioning (cont.)Yesterday…• Online computers switched on• Power enabled to Maratons• LV control computer switched on and appears to be operational• Software + GBit driver (used for VME communication) is updated to SLC4
with updates for station 1 (see next slide)
Today…• Cooling began running• Gas began flowing• ME-2 disk was lowered (i.e., no access allowed)
Weekend…• Access tests disables access to experiment (would be breaking interlock,
otherwise)
Recommence commissioning Monday by “Team-C” (i.e., me)
Step A: download new firmware to all components…

Updates to Online SoftwareUpdates by Jinghua and me include…
• Multiple crates in single xml file
• Remap user access to AFEBs to be from 1 to 18, regardless of how AFEBs are connected to the ALCT
AFEB 1(always)
On ME1/1…
• AFEBs count from 1 to 18 (inner to outer)
• ALCT always mounted with the same orientation (AFEB input #1 to right)
• ALCT slow control firmware the same on all
• ME1/1 mounted on disks with respect to IP as in the picture to the left….
Ordering of AFEBs reversed on
(Plus, forward) and
(Minus, backward)
AFEB 18(always)
AFEB input #1
AFEB input #18

Updates to Online Software (cont.)Added xml parameters for TMB
1. clct_stagger = 1/0 = do/don't stagger strip layers (staggering needed for ME1/1)
2. clct_blanking = 1/0 = do/don't blank CLCT output if no valid pattern flag
3. clct_pattern_id_thresh = [0-8] = minimum pattern ID value for CLCT pretrigger
4. aff_thresh = [0-6] = minimum number of hits needed on CLCT pretrigger pattern to send Active FEB Flag to DMB
5. min_clct_separation = [0-255] = minimum 1/2-strip separation between two CLCTs
• Removed clct_distrip_pretrig_thresh (since no di-stripness left…)

To do…• Clean up simulation drift time analysis for muons
• Remove delta-electrons
• Point source from vertex
• Bin in understandable unit
• Cleanly separate:
• drift time to wire
• minimum drift time to wire for events with multiple wires hit
• drift time from wiregroup
• Make plots in code, not PAW…
• Commission ME+1 chambers
• Write documentation for Team-A
