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….
Problem
OK
• 2nd hybrid bonded fine; programme OK
Make more dummy modules?
Need more patterned glass

S Pyatt
(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)
-Clean-room PC (Win7) with
Atlys connected to Birminghamassembled 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)
•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.
