Fairchild Engineering CCD once more in operation.

Status, May 29th, 2007

The following is a complete set of pictures taken in the new AITC Clean Room
(Room LG1.13), yesterday (May 28th).
These pictures show the Engineering CCD having its handling frame swapped
for a unit which is safer to remain in place with the detector at its operating
temperature, T=-120C.
The handling frame is left in-situ as the detector is very difficult to manipulte
without this in place. The new design is meant to provide more space for the detector
bond wires, and, a new safety feature so the frame can't be tilted and impact the
delicate wires.

Clean Room Picture details.

• 1. Layout showing Handling Jig from MPFI and Detector in box.
• 2. Detector mounted on handling jig with Glass cover in place,
  new frame in background and Mount Block and Flex in foreground
• 3. Detector 'gripper' on the left with securing arrangement so that
  the detector can't be released from grippper!. New frame on the right.
• 4. Mount Jig, showing window & old frame in place - ready to have old
  frame lowered away.
• 5. Close up of Mount Jig, showing window & old frame in place.
• 6. CCD removed from Jig using Gripper. Securing screw yet to be tightened.
• 7. Old frame being removed from the Mounting Jig.
• 8. Gripper, resting on block with securing screw tightened. Device has
  No frame and bare silicon is evident.
• 9. Another shot of the gripper, resting in a 2nd position. Not as stable
  as the first, new frame in background.
• 10. Mounting jig ready to receive new frame.
• 11. New Frame in place.
• 12. CCD now lowered onto mounting jig - ready to have new frame lifted
  into place.
• 13. View of gripper without detector and CCD rest block.
• 14. Gripper holding CCD, Frame renmoved and showing underside of device.
  The copper lug is what we mate to for cooling and the CCD pins have still
  got their shorting arrangement in place. It was the lug, on this device, the
  old science CCD which came off in August last year.
• 15. New frame in place and a novel arrangement of hex drives being used to
  keep the frame located so that the 4 small screws can be installed.
• 16. 2 of the frame screws are now visible, and the detector window is yet
  to be installed.
• 17. Window has now been installed and kapton tape used to secure 2 edges.
  The device is now safe to pick up!
• 18. CCD upside down on Flow bench, showing underside of frame, copper lug,
  earthing strips and the front of the detector mount block with the Flex ready to
  be installed on the CCD pins.
• 19. Close up of the back of the FI Eng CCD #2, grounding strips in place.
• 20. Close up of the back of the FI Eng CCD #2, grounding strips removed.
• 21. Flex connector attached to rear of CCD - grounding plug visible in the
  50-way connector at the other end of the Flex.
• 22. View of the front of the detector, showing mount block, CCD and its Flex.
• 23. View of Detector mounted in the Test Dewar, window still in place.
  After this, the window will be removed and the top of the dewar installed.
  The dewar is then ready for pumping and cooling.
