EPU60 Status
Control system design approved
Control system parts on order; assembly to start in late Feb.
Initial magnetic measurement starting this week
Using old control system
Final magnetic measurements & shimming in April/May
Will know extent after initial measurement
All machined parts complete
New switches on order
Plan to install in summer
Combination of
maint. days & shutdownRack installed on SR mezzSlide9

Front End Development
Most components are identical to previous ID front ends
First canted beamline with two
undulators
Synchrotron fans overlap each other at fixed mask
Original fixed mask has a center web between the two apertures
Required new fixed mask design
FDR for new fixed mask occurred in Oct. ’16
New design is more adaptable, generic, & easier to manufacture
A prototype was produced to validate the machining process
ANSYS analysis & weld testing
were performedMinor upgrade to slit blade designBetter thermal transfer & easier assemblyFront end ray tracing approvedFront end design completeSlide12
Front End Status
All components received, except:
Fixed mask & slits (due in April)
X-BPM head – de-scoped for now
Cable pulling complete
All stands installed in Dec. ‘16
Ratchet wall collimator installed in Dec. ‘16
Cable termination & utilities work in process
Exit pipe from SR to be installed in April
Integrated testing to occur April/May
Under vacuum, bake & final survey to occur in August
Installation to be complete in AugustShutters locked out until IRR approvalSlide13
Conclusion
U42 & EPU60 refurbishment finishing & magnetic measurement starting
One device to be installed in April & one in the summer
Reusing majority of existing front end component designs
FDR completed for new fixed mask
Front end installation far along & will be complete in August
Installation plan developed & integrated with other beamlines
Resources have been identified and leveled
Work
flow experience from
existing NSLS-II beamlines
On track to meet overall project schedule
