DESCRIPTION

STT rack space needs. educated guess of STT requirements. TC is asking for. a) How many U rack space do you need at the detector? b) How many U rack space do you need in the supply level (E10) and the DAQ/readout level (E20) of the counting house? - PowerPoint PPT Presentation

TC is asking fora) How many U rack space do you need at the detector?

b) How many U rack space do you need in the supply level (E10) and the DAQ/readout level (E20) of the counting house?

c) Do you need any equipment close to the detector in non-standard (non-rack) housings? At which minimal distance to your detector and with which dimensions?

The dead line to provide info is next TB in Bochum

4636 Straw tubes arranged in planar layers (24-27)

Time readout (isochrone radius) drift time ~ 200 ns (B=2T) req. electronic resolution < 1 ns sensitivity (threshold) ~ 2 fC

Amplitude readout (energy loss) Straw tube capacitance: ~ 10-15 pF (9 pF/m) impedance: 373 Ώ inductance:1.24 μH/m Gas volume: ~ 1040 l mixture 90Ar + 10CO2

FEE anlog: • Preamp+ Shaper+ BLR + Discriminator Analog output needed for dE/dx measurement?

Digital Boards: • Multihit TDC: Time measurement + TimeOverThreshold

(TOT) for charge measurement OR/AND analog signal processing via FADC

• Zero suppression & Hit detection. Slow /Run/Data flow control

Data Concentration : • gathering and sorting of hits marked by time stamps in

epoques (i.e 500 s bunch)

• nGbit/s Optical serial link

Located on the STT

Located on racks outside

FEE BoardsTentative layout of FEE boards.Total # 592 includes some spare channel.

Cooling is not yet excluded.

Digital+Concentration Boards

5x Lattice ECP3 150 FPGAs • 4 edge devices up to 60 TDC ch• 1 central for control • Flash ROMs for each

• 4x 208pin QMS connectors Small Addons

• 2x80pin connectors Large Addon (i.e. ADC)

24 TRBs will instrument all STT

These functions are implemented in TRBv3.

Which kind of Crates? 9U, 6U How many?

HV system• Based on Wiener Mpod (8U) - universal multi-channel LV/ HV power supply

system- Controller with Ethernet, CANbus, USB interface, and interlock; - Web-ready and TCP/IP communication via SNMP,

OPC server;- LabView software support;- LV and HV modules freely combinable; - High Voltage modules (ISEG) with 8, 16, 32 channels

of from 500V to 10kV, floating or common ground; - Low Voltage floating modules with 8 channels of 10A /

50W max. with 8V, 16V, 30V, 60V ranges- PXI platform from National Instruments as I/O Controller- Embedded controllers with Intel CPUs, hard drive, memory, Ethernet, video, serial, USB, GPIB;- OS support: Windows, LabView Real-time, Linux;- more than 1500 PXI products (Multifun. DAQ, FPGA)

How much space?

Slow ControlsARM-processors (CPU based on simplified instruction sets) will control different field points (gas/pressure controllers, temp. sensors, etc. )

DCS and HV systemsRegarding rack space for the DCS and HV System:

- ethernet switch: 1 U- epics gateway server : 2U- NI PXI Crate: 4U- MPOD Bin: 9U________________total: 16U

Cables and supply lines- The STT readout ASIC will provide LVDS differential outputs. - It will have 8 channels/chip and 2 control lines. Therefore for each chip we will

need a 10 pairs flat cable.Total # of flat cables is 296x2. These cables should be connected to patch-panels locate outside the magnet ~1240mmx1200mmx150mm - For the gas we foresee 24 gas supply lines, 224 gas pipes

(in-/outlet).- We need also 40 HV cables.

- How many control lines for temperature and pressure? - Threshold setting and test pulses for FEE are already included?
