Management
A project close-out letter was signed this week by the DOE Site
Office and the Navy High Energy Laser Program Office officially
recording the end of the IR Demo Construction Project on Sept.
30, 1997. Both offices recognized the project as being "complete
for all practical purposes allowing the IR Demo commissioning
to proceed on schedule". As part of the close-out report,
the summary financial reports were prepared for the final month
of the construction project (Sept.).
Four more pre-proposals from LPC collaborators were prepared this
week for submission to the DOE-BES Program Office. Expressions
of interest on possible FEL user activities received this week
from physics and chemistry faculty from Princeton University,
Univ. of Wisconsin and Univ. of Maryland.
Preparations continued for our participation in the Oct. 27-29
workshop on "Scientific Applications of 4th Generation Light
Sources" at Argonne National Laboratory. Several members
of the contingent who have submitted FEL user proposals have volunteered
to attend workshop working sessions on materials physics and chemical
physics.
Today is the last day of John Albertine's job as Program Manager
for the Navy HEL office. Jefferson Lab wishes him well in his
new career and thanks him for his leadership of the IR Demo Project.
Installation Activities
A punch list of remaining installation activities was prepared
as an appendix for the construction project close out letter.
These activities are being performed during the day shift over
the next month; second and third shift are being reserved for
commissioning activities.
Highlights for installation accomplishments this week include
the following: a test fit-up of a reverse-bend dipole (DQ) in
the east arc; the recirculation dump was installed; supply and
return LCW lines were installed for the east arc region; the girder
assembly for the upstream linac cryomodule connection was installed;
and several components of the gun HVPS elbow were temporarily
removed and modified to improve the stand-off voltage and the
SF6 seal integrity.
Commissioning Activities
The gun assembly was operated at 400kV+ for approximately one
shift to further evaluate the high voltage conditioning of the
assembly. The gun appears to condition to the required voltages
for first light rapidly. After this test, the gun HVPS elbow
was disassembled for the modifications noted above.
RF check-out of the injector buncher cavity continued. The system
achieved 2kW CW and 2.5kW pulsed. On Friday, software for the
cryounit and linac software was being checked out prior to anticipated
SRF commissioning next week.
Software for auto turn-on of the injector was tested, as was control
software for vacuum valve operation.
The drive laser transport optics were aligned and the transport
line for the FEL output was leak-checked.
