IVU Refurbishment Details
IVU was built in 2005 by ADC and was installed in NSLS until its shutdown
IVU was transported to bldg. 832 for refurbishment
A new control system was designed & built to meet NSLS-II standards
New flexible tapered transitions were designed & built to mate with the NSLS-II vacuum chamber
Design review held in Jan. ‘16
A new plinth was required to bring the IVU
to the proper beam height
Correction coils were added
Stretched new foil over magnet arrays
New RTDs, encoders, switches,
& magic fingers added
Magnetic measurement & shimming
Pressure tested
L

Cooling in the IVU straight
The
canting magnets & tapers are cooled from the standard cooling
circuit
T
he
IVU is cooled from an independent chiller
circuit
Due to low pressure requirement (originally designed for
cryo
cooling)
Same model chiller as SRX IVU
There is a small
internal leak from the IVU cooling circuit to the beam vacuum through the insulating vacuumBeing mitigated by pumping on the insulating vacuumBurst disk has been added to insulating vacuumAdequate vacuum is being maintained & commissioning can commence
Planning to repair leak during upcoming shutdown (post-start)Slide10

Safety Features of NSLS-II Insertion Devices
Various safety features have been implemented for all IDs:Brakes in motorsBrakes are on when there is no powerSelf-locking gearsGap will not close by attractive force onlyPilot lamp during gap/phase motionWarns people in the vicinity of the device that it is in motionLOTO procedures during maintenanceWritten procedure for each type of the device for lock-out and tag-outSlide13
EPS Switch For IVUA mechanical switch on the IVU independent from control system for “gap open” status is integrated into EPSSlide14
Front End Details
A front end delivers the photon beam to the beamline while controlling the sizes of both the synchrotron and bremsstrahlung radiation fans.
The
fixed mask
trims the synchrotron fan produced by the ID down to the synchrotron fan required by the beamline.
Lead
collimators trim
the Bremsstrahlung fan exiting to beamlines.
Photon shutter is used to stop the photon beam in order to protect the uncooled safety shutters.
The safety shutters block the bremsstrahlung radiation from exiting through the
ratchet wall collimator
chamber opening.
The photon shutter & safety shutters are locked out
. (Centrally controlled LOTO)Same safety shutter & ratchet wall collimator design as the recent bending magnet front endsOther components are the same design as NSLS-II Project, ABBIX, & NEXT front endsSlide15

Commissioning Plan
Commissioning scheduled for mid-Nov ‘16
Beamline commissioning
time reserved
Commissioning effort will include staff from Operations, Physics, Insertion Device, Front End, and Diag. groups
Software controls & tools already developed and verified during NSLS-II beamline commissioning
Procedures released for ID & FE commissioning sequence and radiation survey plan
Same commissioning plan as other recently commissioned IDs & FEsSlide20
