MICE/AFE II t Update

  • IIT Analog Front End (AFE) Test Stand

  • AFE Conceptual Design Report (CDR)

Terry Hart,

Illinois Institute of Technology,

February 10, 2006


Afe ii t overview

AFE II t Overview

  • The D0 Central Fiber Tracker uses AFE I boards to collect digital hit pattern and charge amplitude information from input charge signals.

  • AFE II boards were developed as prototypes for the D0 upgrade to AFE II t and have been used by MICE for the KEK test beam.

  • A D0 upgrade of the AFE II boards is a modified chip which will provide timing information (AFE II t).

  • MICE fiber trackers will use AFE II t boards for the data readout.

    - The MICE group will assist in the testing of the AFE II t boards.

    - An IIT test stand will be assembled soon.

    - Another RAL test stand will be set up in late March.


Afe ii test stand at d0

AFE II Test Stand at D0

  • Two AFE II boards installed in one of the two cassettes of the cryostat.

  • Cryostat will be tilted by about 20° and temperature stability will be checked.

IIT AFE II t Test Stand

  • IIT People: Dan Kaplan, Terry Hart, Bill Luebke, Dan Olive

  • Key contributors: Paul Rubinov, Malcolm Ellis

  • We have most of the hardware components at Fermilab and IIT. The IIT test stand will be set up at Fermilab.

    • Computer with diagnostic software

    • VME64 to PCI adapter with fiber optic cable

  • We are expecting one of the 16 AFE II t pre-production boards soon.

IIT AFE II t Test Stand

  • Bob Angstadt has installed driver for SBS 810 VME 64 to PCI adapter and diagnostic software on our computer.

  • Single word and DMA block transfers work (See next slide.).

  • We will also learn about

    • Further hardware tests with the IIT AFE II t test stand.

    • What AFE board tests we should do specifically for MICE.

IIT Test Stand Anticipated Schedule

  • D0 AFE II t production schedule

    + Next week: Receive 16 pre-production boards.

    + Feb. - March: Test pre-production boards during D0 data taking.

    + March - May: Debug and fix pre-production boards.

    + May - June: Full scale production of AFE II t boards.

  • Learn about AFE II t boards by helping D0 with their test stand - now through next few months.

  • Learn about FPGA programming and firmware necessary for MICE operation of AFE II t boards, and define requirement by mid-2006.

  • Have working hardware (16 boards + spares) by Fall, 2006.

AFE II t CDR

  • Preparation of a CDR of the AFE II t board is underway and an initial draft is being reviewed.

  • The CDR will include

    • MICE, ISIS, and AFE board introduction and motivation

    • Block diagram and/or schematic drawing of the AFE boards

    • Specific requirements for various data running modes

      • Charge and time data

      • Discriminator data

    • Requirements for achieving data acquisition of as many as 600 muons/ms from current capability of 225 muons/ms.

  • This may develop into a Technical Reference Document (TRD) for the AFE II t for MICE.


Afe ii t data rates

AFE II t Data Rates

  • VME to PC data throughput should be fine for MICE

    - If MICE uses a data word format similar to that used for the KEK tests, each muon event with charge and time information will have about 65,280 bytes.

    - (600 muons/sec)(65,280 bytes) = 37.3 MB/sec.

    This is achievable with the 47.4 MB/sec capability mentioned earlier.

  • Full digitization of charges and times limit reconstruction rate to about 225 muons/spill.

    - Total digitization time for 32 channels on a TRIP-t chip is about 4.4 s or about 225 muons/sec.

    - If only discriminator information is used (Hit or no hit?), maximum instantaneous rate is about 7000 muons/sec.

    - MICE/AFE II t CDR discusses this in detail.

MICE/AFE II t Plans

  • Prepare CDR and TRD.

  • Set up IIT test stand to become part of the D0 AFE II t tests.

  • Determine special MICE requirements and test AFE II t boards for these.

  • Set up RAL test stand for tracker quality control.
