VXD Cooling Requirements & Specs
Minimize material in acceptance region
SVD requirements:
coolant temperature for APV25 @ -20°C for SNR improvement
total dissipated power ~ 700 W
PXD requirements:
sensor temp. < 25°C, ASICs < 50°C : cooling block @ <-20°C
dissipated power ~ 360 W
Cooling power ~ 1.6 kW at VXD (incl. ~ 540 W parasitic heat influx)
have to add heat loss through 15 m of transfer lines → ~ 2-3 kW
Dry Volume (preferably nitrogen):
dew point inside VXD volume: ~ -30 °C
Outside of VXD: room temperature ( ~ 23°C) at the CDC
may need a thermal enclosure towards CDC, well isolated

Commissioning of IBBelle at CERN
Installation at CERN (ATLAS Experiment): the “twin” of IBBelle
Accum.
rack
Construction of IBBelle (ATLAS) is finished
Commissioning with dummy heat load is
mostly done
Some problems getting down to -40°C
(not important for the Belle version)
Now testing all CO2 connections to IBL

Control of Accumulator Loop
uses PLC
industrial
standard
(“Schneider”)
programming done
by CERN
(MARCO and
IBBelle)

PVSS -> EPICS
Remark: This is a desired option, not a necessity

PVSS GUI for IBBelle
Plant A
PVSS sets operation
points (T, CO2 flux)
and monitors the
operation
Supervising layer
(+GUI) will be
re-written in
EPICS / CSS
(Michael, Bogdan,
Thorsten)
All critical control /
operation functions
are formulated in PLC
and will not be
touched

Interlock CO2 <-> Detector
The CO2 system can be in anyone of three operational states:
(simplified scheme)
DAQ only if in “Run”
Mode
States
“Operation”
“Stop” <-> “Run” (manual, automatic, interlock, swap)
“Stand-by”
“Stop” <-> “Run” (manual, automatic, interlock)
“Maintenance”
“Stop” (all actuators in “safe position”, all interlocks
disabled, manual )
Transitions between states managed by sequencer (“recipes”)
Alarms issued by sensors (temperature, flow, pressure)
Actuators: control point (valves, motors, mass flow controllers, etc.)
for each a “safe position” is defined
C. Kiesling, 6th Belle II PXD/SVD Workshop and 17th Intl. Worshopp on DEPFET Detectors and Applications, Pisa, Oct. 1-3, 2014
9
Interlock CO2 <-> Detector
Types of Interlock (unit or actuator)
“Full Stop Interlock” (FS): Stop unit/actuator, wait for manual acknowl.
“Temporary Stop Interlock (TS)”: stop unit/actuator, resume automatically
when Interlock disappears
“Start Interlock” (SI)
prevent unit / actuator from starting
Types of Alarms
“Warning”
“Alarm”
message
message, set appropriate interlock type
Depending on interlock type, hardwired signal to “interlock box”
(e.g. : “FS” leads to VXD power switch off)

Documentation of the CO2 Plant
Production drawings for the mechanics exist, part lists as well, but
-
Need to go through the drawings and tables to establish part list
-
MPI working on this: Sven Vogt
-
Status: Swagelok part list almost done, offers have been asked for
waiting for definite quotes
For the control side (PCLs etc), things are not too well documented:
-
MPI working on this: Reinhard Sedlmeyer
already two visits at CERN to establish status in situ
-
First parts have been asked for quotes and are ordered through CERN
Process of getting quotes and do the ordering will take till the end of year

11
Construction and Commissioning
IBBelle for VXD will be an EXACT copy of IBBelle (ATLAS)
Variants possible in the transfer system from IBBelle to VXD
(include results from Thermal Mockup)
Up-to-date 3D CAD model and production drawings exist
Ordering of parts according to lists established at MPI (based on material
from CERN/Nikhef for ATLAS IBL) by MPI
Construction at MPI starts in 2015 (workshop is prepared), including
pressure tests, control electronics, etc.
Commissioning will be done with the help of CERN/Nikhef crew (exact
dates to be organized) by the end of 2015 at MPI, including engineers
from DESY, KEK and SVD (tbd)
Certification by TÜV (process being prepared at present)

than needed

Location of the CO2 Plant at KEK
Space tight, but adequate
Potential problem: Access to top of Belle II

16
Alternative Arrangement
40’ Container, to be placed outside of Tsukuba hall
Advantage: unit can be assembled at MPI, no need to
take it apart for transport, no reassembly
Potential problems:
need water/electricity outside hall
Need to air condition the container

Schedule for the CO2 Plant
IBBelle at KEK
in summer of
2016

Responsibilities, Operation at KEK
Lead institute (main responsibility): MPI Munich
Collaborating institutes: DESY + SVD (tbd)
Installation at KEK: MPI, DESY, SVD (= “VXD”)
Commissioning: VXD + KEK
(Kimura-san, head of KEK cryo group visited IBBelle at CERN in April 2014,
next meeting on October 6/7, 2014 )
Agreement with KEK (Nov. 13 B2GM meeting):
KEK will operate and monitor IBBelle
standard service tasks executed by KEK
(e.g. filter cleaning, replacement of spare parts)
major failures will require action by VXD crew
