CCD changeover

Back to Sample Alignment Quick Reference

This reference is intended as a checklist for staff or advanced users - steps are outlined with a minimum of detail

1) Exit CCD software
Access computer Mahler on a KVM station - bring up CCD Image Server software, hit File then Exit

NOTES:
i) If the SPiiPlus software is on and the Coolsnap focus motion is still connected, make sure the amplifier is disabled (hit disable motion for axis 0 on the motion control screen)

2) Power down CCD
When removing Coolsnap detector switch off small rocker switch on back, then rocker switch on the larger bottom power supply on detector arm, disconnect data and power cables, and organize cables for focus motion
When removing PIXIS 1024XF detector switch off rocker switch on the smaller top power supply on detector arm, disconnect data cable, power cable, and logic out - shutter BNC cable
When removing PI-LCX detector unplug controller power cord marked PI-LCX on outboard wall, disconnect large data cable (first slide retaining clip to the left), disconnect controller-shutter BNC barrel

NOTES:
i) Make sure amplifier is disabled for focus motion prior to disconnecting any cables

3) Remove / replace CCD
All CCDs dismount with 3x 10-32 screws on the base, then slide straight out, gently rocking if necessary - mount new CCD in the same way

NOTES:
i) Be extremely careful jostling Coolsnap tube lens - treat as if it could strip out from the face at any moment
ii) Place Coolsnap on its right hand side with the nanomotion motor facing up when storing

4) Connect / Power up CCD
When mounting Coolsnap detector connect data and power cables, switch on the larger bottom power supply on detector arm, then switch on small rocker switch on back
When mounting PIXIS 1024XF detector connect data cable, power cable, and logic out BNC - shutter BNC cable, then switch on rocker switch on the smaller top power supply on detector arm
When mounting PI-LCX detector connect large data cable (then slide retaining clip to the left to lock), and connect controller logic cable-shutter BNC cable with a barrel, then plug controller power cord marked PI-LCX on outboard wall

NOTES:
i) After power on, verify the cooling fans on the mounted CCD are moving

5) Select appropriate shutter mode
When mounting Coolsnap detector set flick switch on Aszol shutter control at front of hutch to Manual Open (green light should be on)
When mounting PIXIS 1024XF or PI-LCX detector set flick switch on Aszol shutter control at front of hutch to Remote Control

NOTES:
i) Audible clicking should be heard when flick switch is cycled
