UG-electronics Update

• Feb. 5th 2008
• A.Bartoloni, B.Borgia, F.Spada

2
UG-electronics in the TRD Gas System

QM design

• Design of control electronics from EM to QM
  updated after test session in August 2004
• Contract issued to GA Engineering for
  construction and qualification of QM and FM UG
  electronics ? February 2005
• Radiation test of few components performed at
  Karlsruhe, under the supervision of Andrei
  Kounine, May 2005
• Further modifications were introduced because of
  gas circuit changes, e.g. 24V to 30V

4
EM ? QM

• Change power supply 24V?30V (supply for Kulite,
  Marotta valves, pumps, heaters)
• Pumps power supply 12V directly from DC-DC
  converter, 24V with step-down circuit 30V?24V.
• Heaters x CO2, Xe vessels on/off switches
  identical to Marotta valves switches
• Added Kulite gauges
• Dallas T sensors replacing GP-50 T n. 2
  dedicated links to USCM

• Safest valves operation in magnetic field
• Pumps variable load
• Need to control vessel temperature
• Need pressure measurement reliability
• Add temperature measurements

No basic circuit was modified, i.e. ADC,
switches, serial link QM FUNCTIONALITY TEST JULY

Components

• TIM January 2007 questioned several elements in
  components list
• Kounine revised the components list and marked
  the following ones
• TPS73xx on AMS component list marked as
  NON-FLIGHT
• SUB85N10-10 not on AMS part list
• HI-508 not on AMS part list
• AD620BR not on AMS part list
• GA provided documents on rad test. The only
  remaining non flight was TPS73xx
• TPS73XX can be replaced by LP2989, latch free.
• LP2989 is not pin to pin compatible, therefore
  needs a new layout and a new PCB

6
QM to QM2..

• Following the change of linear regulators
  TPS73xx, of power distribution scheme and several
  changes required by safest operations (short
  circuits on cables or components),
• we had to design new QM UGxx boards with
  following major modifications
• replace the TPSxxxx regulators with SEL free
  LP2989 (UGBS, UGBC, UGFV)
• put limiting resistor on Kulites and GP50 power
  supply lines (UGBS, UGBC)
• separate 12V power supply for UGPS and flipper
  valve (UGFV)
• introduce LP2953 regulator to generate 24V for
  pumps high speed (UGBP)
• introduce LP2953 regulator to generate 21V for
  analog mux (UGBP)
• eliminate 3.3V DC-DC converter ?generate 3.3V
  from 5V on backplane
• introduce Solid State Fuses (SSF) for short
  circuit protection on 5V, on each module
• introduce pull-down resistors on Mosfet gates
• introduce differential amplifier on Kulite inputs
• eliminate UHVG (?redesign of backplane)
• eliminate 2 UGFV and reduce 8 multiple channels
  to 4 (?redesign of pcb)

UGxx specifications

• First draft v 1.4 (26/02/02)
• Draft after EM test v 3.6 (17/05/05)
• Last draft v 4.2 (26/06/06)
• In preparation v 5.0 (2008)

• QM1 UG-electronics currently used for Gas System
  tests
• UG slow-control software and user interface used
  successfully on QM1 and QM2 UG-electronics
• QM2 UG-electronics under functionality test
• QM2 UG-electronics qualification scheduled at
  SERMS on feb 11th

Qualification and acceptance tests
Guidelines for the qualification and acceptance
tests of the AMS-02 electronics (Notes compiled
by G. Ambrosi for the AMS-02 Sub Detector
Electronic group, September 28th 2005. Feedback,
comments and corrections are welcome.) In this
short report are summarized the guidelines for
the definition of the qualification and
acceptance procedure to be implemented for all
the box electronics of the AMS--02 experiment.
The information and specifications reported are
derived from the discussions within the
Sub-Detector Electronics group, from the
indications of the CSIST people and from the
experience gained with the test of J/JT/JPD
crate. The guidelines reported here do apply to
the following hardware (for the detailed
nomenclature and list look in the Flight Design
) U- , T- , S- , E- ,J- , JT- ,TT- , UG- , M-
crate UPD, TPD, TSPD, ERPD, JPD, UGPD, TMPD,SHV,
RHV, EHV As a general rule no design
modifications are allowed between the QM and
FM/FS.
