Birmingham update: making modules? ASICS to hybrid

Gluing: many trials

i) heated plate with silver loaded (8 hybrids i.e. 1 panel per day)

ii) UV cured glue (glues not quite in hand; which glue?)

Luise via email: make electrical

EC hybrids with various glues; irradiate (at KIT) : choose the best .

Bonding: bonder exercised and programme

Hybrid to sensor

Gluing: two modules made (mechanicals).

i)OK on 2nd attempt

– no bleed.

Bonding

i) Practise on Cu tape.

Birmingham: practice modules Hybrid to sensor

Bonding (contd)

ii) Patterned ASICs to mechanicals.•No problem bonding to Si.•Difficulty bonding to patterned glass: first hybrid only; better after cleaning with alcohol but….

•2nd hybrid bonded fine; programme OK

Make more dummy modules? Need more patterned glass2

(After Steve’s presentation on 16July))

£13.62 each from Farnell;requires a 5 Vdc supply;draws 200 μA;almost linear voltage output vs % RH

HIH-4000: conclusions:

• Will help with optimising the N2 purging of the ALiBaVa freezer.

• Low cost and easy to set up.

• Low power. Could be run off a battery or a modified USB supply.

• Can be used with the Data logger. Either use the front panel display on the data logger or invest in a licence (About £500) to allow real time graph monitoring. Also capturing of the data for export to a spreadsheet.

• Simultaneous monitoring of temperature (with a thermocouple) and %RH can be achieved with the data logger. 20 channels of monitoring are available.

• Also try to use in cold box in cyclotron irradiation.

Atlys+ABCN250-Hybrid at B'ham (1) (Juergen, AndyC, SimonH)

John Wilson, Phil Allport, Simon Pyatt, Sam Edwards, Juergen Thomas, James Broughton, Kostas Nikolopoulos, Andy Chisholm, Simon Head

-Clean-room PC (Win7) with Atlys connected to Birmingham-assembled Stave09 hybrid, ‘B1_H6’ -Now using LVDS Driver Board (at 4V) and 1m tw. pair cable-Powering Hybrid at 2.5V, readout fine, draws ~3A during tests. (Before: ~3.3V, >4.5A) -Now running ‘script mode’ (‘.x myTest.cpp’): No more GUI clicking, no need to sit next to system -> Run for many hours using loops.

Atlys+ABCN250-Hybrid at B'ham (2) (Juergen, AndyC, SimonH)

John Wilson, Phil Allport, Simon Pyatt, Sam Edwards, Juergen Thomas, James Broughton, Kostas Nikolopoulos, Andy Chisholm, Simon Head

•Taken TrimRange run and loaded values into SCTVAR/config (see output below): Much smoother outputs, slimmer histos•Next steps:

•Get better in running script mode. •Run again with second hybrid (‘B2_H7’, our best production-wise).•Setting up a Linux (SLC6) PC in lab, already compiled DAQ s/w on SLC6 (using ‘waf’). When done, connect Atlys and hybrid.
