> > TUDA was successfully re-installed on SEBT1 by LB, TD, AML and PM. > Alignment checked by pillar mounted telescope downstream of HERACLES > and target ball between SEBT1 bending magnet and diagnostic section. > With minor adjustments of upper stage table the upstream and downstream > targets were within 15 thou L-R/U-D. Upper stage table and feet locked. > > 14.00 Cryo pumped by TUDA2:BP5 to <100mTorr > TUDA2.RVC5 closed and cryo compressor switched on > See attachment 1 for EPICS log > > Note: MiniSys Eye-IMG ion gauge installed (EPICS readout only) > > Re-entrant flange assembly installed - currently the 'window' NW25 > fitting is open. > > Centre target ladder linear translator re-installed. Note the > downstream linear translator needs to be moved to the upstream > position. > > 18.28 Time from 1 bar to 250mTorr ~12m (turbo ON) > Time from 250mTorr to 5.0E-4Torr ~5m (cryo ON) > > Note: Transients in TUDA:PNG5:RDVAC when cryo gate valve opened > Observed pressure decreases to <1E-10Torr (PM tells > me that for this gauge this effectively means 'off' > cf. the usual TUDA ion gauge which reads high when 'off') > > Time from 5.0E-4Torr to 5.0E-05Torr ~6m ('good' vacuum) > > Total pump down ~24m (empty chamber) > See attachment 2 for EPICS log > > 07.32 Tuesday 12 April > See attachment 3 for overnight EPICS log > TUDA2:PNG5:RDVAC 7.2E-07Torr
