Status of detectors (update/corrected)

• 16 ERAMs on bot TPC + ERAM-12 (large RC) and 35 (200 kOhm) as spares (at JPARC)

 

• Global Status of ERAMs production for TOP TPC

ERAM-07 : pb seen when bot TPC assembly (not short circuit but too much dust and mesh hole ! )

ERAM-11 : mounted on bot TPC !

ERAM-14 : mounted on second test box in large clean room. to me removed and staored

ERAM-15 : mounting pb on bot TPC --> checked OK at saclay --> usable. at Saclay

ERAM-16 : cc repaired

ERAM-20 : large gain in border

ERAM-27 : THE "surplisingly good" one from bad batch 25-34

ERAM-36 small spreading issues

ERAM-37 small spreading issues

ERAM-39

ERAM-40

ERAM-41

ERAM-43

ERAM-44

ERAM-45

ERAM-38

ERAM-42 (to be confirmed after scan this week) glued on new stiffener

• ERAMs considered "last choices" for TOP TPC

MM1-DLC2 (ERAM-00 in database)

MM1-DLC1

ERAM-25 : bad batch, gain gradient : cards reused

ERAM-33 : bad batch, gain gradient : cards reused

ERAM-34 : bad batch, gain gradient : cards reused

 

ERAM-18 : RC/2

 

• first selection of "first choice" ERAMs for TOP TPC : 15 ERAMs + 3 (ERAM-46-48)

ERAM-14

ERAM-15 : mounting pb on bot TPC --> checked OK at saclay --> usable

ERAM-16 : cc repaired

ERAM-20 : large gain in border

ERAM-27 : THE "surplisingly good" one from bad batch 25-34

ERAM-36 small spreading issues

ERAM-37 small spreading issues

ERAM-39

ERAM-40

ERAM-41

ERAM-43

ERAM-44

ERAM-45

ERAM-38

ERAM-42 tsvan to be confirmed, glued on new stiffener)

• remaining ERAMs = 3 ERAMs

to glue

ERAM-46-48

 

to scan

ERAM-46-48 withb cards 1,5,6,11 and 15 - 76 (from ERAM-33)

ERAM-42 (this week)

 

ERAM-39 or 40 to rescan with cards 80 and 84 (from ERAM-27) (they both use cards 7,10 !)

 

• Status of FEC cards available at CERN

remaining to be used

 

1, 5, 6, 11  (blue cabinet) + reused 15, 76 to scan ERAM-46 47 48

 

73 the only one to rescan ERAM-39 or 40 which were scanned with cards 7, 10. a c ard is missing to rescan this eram.

 

missing card : 44 

card 73 alone ? with fec 37 which was damaged and repaired .... originally affected to ERAM-12

to check : the 4 cards at Tokai which should have been  the ones affected to ERAM-15 and 12 (54, 37) and (44, 24)

BUT 24 and 37 are at bdg 182 ! 44 and 54 are missing. And the 4 FEC cards at JPARC are 14,72, 30, 35 !
