Installing tent. Two NEG power cable broken. |

09.28 Pirani 1.00e-3 mbar IE514 5.45e-8 mbar
12.10 Bakeout tent frame installed
SAES UHV1400 NEG pump power cables #1-6 installed
See attachments 1 & 2
16.35 Attachments 3-6
upstream baseplate
3x sets of heaters beneath CARME chamber connected to CRYRING heater/TC manifold - attachments 7-8
16.45 Pirani 1.00e-3 mbar IE514 4.80e-8 mbar
17.10 SAES D-2000 #1 downstream, outside NEG power + HV ( attachment 9 - OK cable connector )
SAES D-2000 #3 downstream, inside NEG power + HV
SAES D-2000 #4 upstream, inside HV
SAES D-2000 #2 upstream, outside HV
2x ( of 4x ) SAES D-2000 neg power cables were broken - forward-shell detached (unscrewed ) from back-shell remaining attached to D-2000 neg power connector.
Re-assembly is straightforward but it is unclear how the 6x female sockets are aligned with the connector keys of the forward-shell (attachments 10-11 cf. attachment 9).
Until this is understood these 2x SAES D-2000 neg power cables should not be used. |
