09.15 Following overnight pumping of CARME chamber by Leybold turbo
Pirani 1.00e-3 mbar IE514 2.83e-7 mbar
The Leybold IE514 gauge currently in use is the CARME unit ( serial # 1054 ). The calibration data can be found at https://elog.ph.ed.ac.uk/CARME/56
09.44 Pirani 1.00e-3 mbar IE514 2.71e-7 mbar
10.10 Leak tester attached to backing line
Valves to leak tester and turbo (connection to Edwards scroll pump in between) closed.
Stop Edwards scroll pump with magnetic valve 'red' button - magnetic valves closes and Edwards scroll pump is switched off.
Open valves to leak tester and then (slowly) turbo.
Wait for leak tester to settle in e-12 mbar.l/s range. Leak tester pressure 3.6e-3 mbar. IE514 2.69e-7 mbar.

Leak testing.
Downstream DN100 flanges from CARME to dipole OK
Lower NEG power connector feedhtrough (downstream chamber) OK
Left hand side (looking downstream) bellows OK
c. few e-9 mbar.l/s leak bottom left (lookimg downstream) of COF600 wire seal
Additional torque to M16 bolts bottom left - c. 10 bolts -> 220Nm+
c. 0.1-0.3e-11 mbar.l/s
Further checks around circumference of COF600 seal reveal some small leaks c. e-11-12 mbar.l/s.? However background rate
in leak tester too high for sensitive test - will await recovery to resume checking.

Pirani 9.8e-4 mbar IE514 1.87e-7 mbar
15.40 c. few e-9 mbar.l/s leak around magnetic valve - probably not an issue in terms of backing performance but may interfere with/confuse leak testing
16.05 Pirani 9.8e-4 mbar IE514 1.74e-7 mbar
Leak tester 1.2e-9 mbar.l/s
Will leave CARME pumping with leak tester on roughing line and see whether leak rate recovers. If so, will continue leak tests tomorrow.

Leak tester c. 3.5e-12 mbar.l/s (leak tester valved off)

Leak tester c. 4e-10 mbar.l/s (leak tester connected to CARME roughing line)
10.55 Leak tester remains at few e-10 mbar.l/s - we do not understand why
With leak tester in differential mode the highest reading around the COF600 seal is c. 3.5e-12 mbar.l/s
Following checks elsewhere on the chamber we observe c. 6e-12 mbar.l/s which presumably reflects accumulation of He around the chamber
Dispersing He with compressed air reduces diff mode reading to c. 2e-12 mbar.l/s

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. |

The CARME bakeout monitor shows recovery from test yesterday evening. The ELOTECH controller was switched to manual mode for the 3x CARME zones and 5% power selected
for 45 minutes. CARME TCs increased from mid-20s to high 20s/low 30s over a period of 45 minutes. At the conclusion of the test power was set to 0% for all 3x CARME zones
and the mode changed from manual to controlled. |

Set all ELOTECH PID temperature controller zones ( channels ) to 50 deg C
Expect all non-CARME zones to reach temperature set point quickly. There will be a delay for the TCs corresponding to the CARME heaters but the internal CAME TCs
will respond more slowly- will observe response of CARME TCs over time.
