The HE1 Probe was reinstalled into the cyclotron this morning following Section 3.2 in Document-126165 (to be reviewed and released after camera view screen captures added). The procedure took approximately 1 hour from when the trolley was moved into the cyclotron tank until when it was removed. Camera view screenshots were captured throughout the procedure and the probe head was inspected with the left outrigger camera after installation to check for abnormalities - none found.
In Step 3.2.7 of the procedure view #6 was checked to ensure the inner-member was fully retracted before actuating the stop tab - consensus was reached among Remote Handling and Probes Group personnel that the inner-member was fully retracted, but in fact what appeared to be the pulleys at the end of the inner-member in the camera view was actually part of the inner member frame. The stop tab hit the inner-member when it was actuated pushing it backwards. No damage was caused, but a note will be added to the procedure to avoid this in the future. Other than this the installation went smoothly and there were no deviations from the procedure. |
