1. L0 insertion story
we brought in set of L0 scintillators to try installation using EB enfourner+poutre.
we could not do it (many space conflicts).
next attempt, most likely after magnet test, when HCAL is out of magnet and filled up
with EB modules. tooling being prepared for it.
2. HB+ cabling (rbx->towers, towers->gb)
four bottom wedges have been cabled up:
HV RBX->green barracks (no splice boxes)
LV RBX-> tower on far side
DCS RBX-> tower on far side
tower is equipped with PowerDistributionBox (PDB) with 380V/3phase.
on the tower, we have:
AC/DC converter (380V->48V)
one Easy crate with 3 A3016 modules
LV p. panel
DCS hub
from Yb0 tower, we have cables going to green barrack:
LV 48V service cable
dub power supply cable
communication cables for hub->DCS ps and Easy crate->CAEN mainframe
extra two cablesDSS (unused as of now)
3. bbgb i&c
in gb, we have:
rack1: three 9U crates (standard 904 version).
first two will do 8 20deg sectors of combined HBHE.
third one will be used for HO.
rack2: three RM->HTR patch panels, installed, ready to be cabled up
rack9: four HV power supplies, LV mainfame, delta p. supply for 48V service line for
LV system.
4. remaining installation tasks (as of tuesday evening)
hoping to have access to HB+ wedges by wednesday/thursday
hope to reach operational stage for lower HB wedges by may 12th (LV, HV, DCS)
hook up service voltage for DCS hub on YB0 tower
install 3rd A3016 into Easy crate on YB0 tower
install air supply for HB+/Near side air driver
install rails for HB+ air driver + install air driver by friday
install air driver controller into gb (rack #9)
install LDB and Laser cables (to RBXes and from Laser (- alcove, in gex/jura corner)
prepare/install grounding straps
glue psd tubes coming out of indexer bar, plug in unused holes
connect OF cables for HB(s14-17): 8*5003, 2*5014, 1*5019 with 4m extensions
full cabling of HB+/top wedges
water system pressure test
N2 inertion system for minus and plus side HB
5. HE+ installations:
PDB on YE+1, far side
48V power line to Easy crate on Near side (AC/DC only on YE+1(far side)
air supply to source driver on YE+1(3rd position)
PSD control cable (from near p. panel to green barrack)
48v serice line for LV and DCS rub
6. hcal operations ducumentation
ahead of may 19th, magnet test readiness/safety review,
we are preparing a set of short, simple operating manuals for HCAL.
see website with few drafs posted:
http://sx5-hcal.web.cern.ch/sx5-hcal/operations-manual/operations-manual.htm,
please constructively critisize (what to add), send me also your docs, for sections
that are missing.
target date to have reasonable set of manuals: may 12th.
7. cables for ux5 status
need to make inventory of HV, LV cables (wrt to what we need)
need to start putting aside/labeling cables for YE+1/near side
status of 5019 delivery?
laser timng (HB/HE/HO/HF?)
8. HF
wire sourcing in histogramming mode was completed last friday.
thanks and congratulations to all wire-source shifters.
more raddam data was taken over the weekend, first impression is that
numbers look consistent with earlier data (taken before w.s campaign started)
remaining tasks:
normal mode (random trigger, non-histogramming) calibration with w.s.
triggered mode calibration with w.s.
??? (more HF discussions tomorrow at 3:30pm)
we were asked to complete all calibration tasks on/before may20, in order to start
preparing HFs for transport to sx5 sometime july3-12.
