LBNL/APS Collaboration on Fast CCD
Development10-25-2006
  • By John Weizeorick
  • Argonne National Laboratory
  • Advanced Photon Source
  • X-Ray Science Division
  • Beamline Technical Support

Station Identification
  • Beamline Technical Support
  • Who
  • Patricia Fernandez
  • Lisa Gades Kevin Beyer John Lee
  • Troy Lutes Tim Madden Antonino Miceli
  • Diane Morgan Steve Ross Rick Spence
  • John Weizeorick
  • What
  • Detector Pool
  • Equipment Pool
  • Point-of-contact between APS user community and
    Argonne/APS service groups and contractors
  • Provide assistance to beamline staff on
    construction/upgrade, repair errors and project
    management assistance
  • Working on Detector Development and Beamline
    instrumentation

FCCD Project - History
  • SNAP - (Supernova / Acceleration Probe)
    Proposed space based telescope
  • SNAP CCD
  • CCD Mosaic camera ( half-billion pixel imager)
  • Being Developed by Custom Integrated Circuits
    group at LBNL lead by Peter Denes
  • SNAP Readout IC - LBNL
  • Thick, (gt200 µm), Fully depleted,
    back-illuminated CCD imager
  • Howard Padmore (ALS) and Peter Denes at LBNL
  • Realized SNAP CCD has characteristics that are
    useful for X-ray CCD
  • Back-illuminated Higher optical quantum
    efficiency
  • Thick Has enough mechanical structure that it
    can be used with a fiber optic taper, and can be
    used for direct x-ray direct.
  • Bought space on SNAP wafer run to build a Fast
    CCD
  • SNAP CCD modified to achieve faster readout
    (almost column-parallel)

FCCD Project - History
  • SNAP 6-inch wafer

Fast CCDs 30 µm pixels 480x480 metal
strapped 350x380 metal strapped 4 port 480x558
non-strapped 4 port 20x480 metal-strapped

FCCD Project - History
  • Fast CCD
  • 480 x 480 (30um pixels)
  • Thick and back-illuminated CCD
  • Good quantum efficiency (QE) for phosphor coupled
    x-ray cameras
  • Thickness of 200-300 um (Fully Depleted)
  • X-Ray Direct detection
  • Added Almost Column-Parallel Readout
  • Split Top and Bottom of CCD and have one output
    for 10 columns
  • Readout time of 2.4 msec / frame max of 416
    frames/sec
  • 192 Mbytes/sec
  • Custom Readout IC to perform ADC on 96 analog
    outputs
  • 16 Analog Inputs 14bit outputs
  • Conversion Rate of 1usec/pixel
  • 4 Serial LVDS output
  • Both CCD and Readout IC are based on SNAP design

FCCD Project - Collaboration
  • SPIE Conference 2005 (International Society for
    Optical Engineering)
  • Howard Padmore gave talk Fast CCD-based systems
    for detection of x-rays and electronics H.A
    Padmore, C.J.Bebek, M.Church, P.Denes,
    C.R.M.Greaves, S.E.Holland, H. von der Lippe,
    Lawrence Berkeley National Lab
  • Steve Ross attended talk and meet with Howard
    after presentation
  • Discussed the possibility of collaborating with
    LBNL in the development and fabrication of x-ray
    detectors based on these fast readout CCD chips.
  • 2005 Meetings with LBNL in October and December
  • LBL has expertise in IC design
  • ANL has expertise in design and fabrication of
    CCD-based x-ray detectors especially in the
    opto-mechanics and data acquisition electronics
  • Sent out letter to beamline scientist and users
    to get input and verify interest
  • At end of these meetings it was agreed that we
    would work together on developing a Fast CCD
    x-ray detector based on LBNLs CCD.

FCCD Project - Status
  • LBNL
  • Expect FCCD from DALSA in mid November
  • Disadvantage of sharing wafer run - There
    problems are your problems
  • Received FCCD Readout Chip (fCRIC)
  • Initial testing of fCRIC looks good
  • Started putting together mechanical mockup of CCD
    assemble
  • Have Vacuum chamber in house
  • ANL
  • Two of three schematics are finished and are
    ready to be laid out
  • Started simulating portions of the FPGA Code
    related to fCRIC interface
  • Have two Coreco Frame Grabbers (Full Camera Link)
  • LBNL and ANL
  • Numerous Video Conferences and a few visits to
    each others lab
  • Matthew Church and James Glossinger visit -
    watched assemble and testing of our vacuum
    housing.
