NEG pump electrical connections tested - all connections sound.
Detector carriers have been redrilled and are currently being cleaned. Carriers were checked within the chamber, mounting much easier with new hole. Distances to NEG feedthroughs and thermocouple feedthrough from the carrier also checked. NEG feedthroughs have sufficient separation now moved, thermocouple required moving to top flange position to avoid collision with carrier.
Longer external thermocouples required for top position to reach TC08's. 3 Longer thermocouples made up using spare wire and connected to feedthrough. All thermocouples checked using baking code - all appear fine. We have 2 long thermocouples for the interaction chamber, 2 for the RE-72's and one for the top of the chamber left. Bellows can be reached by shorter thermocouple. This should be sufficient for baking.
Standoffs job submitted to workshop for production, may be available end of the week depending on schedules of workshop. Clamp guide and hook tools produced.
Cable connectors have started to be seperated and bound into 16 and 17 cable bunches to enable a good fit in strain reliefs. Upon inspection D-connectors were attached upside down and required flipping to correct position (see image - thumbs up indicates correct position). Cables fit through funnel strain reliefs well, other strain reliefs look more difficult - may require more hands to complete. One long connector has criss crossed wires which may not fit in strain reliefs and may require re-wiring a few cables and one long has broken D-connector. Broken ceramic can be replaced with new D-connector and other long connectors are available
Damaged detector removed from carrier and is in its box - awaiting delivery of other detectors.
Interaction chamber mounted on its frame in CRYRING as well
