Restoration Work of Building

After evaluating damages (e.g., crack width) in
concrete-bases for roof-poles in Klystron gallery, therestoration plan has been made (Right photo).

Restoration work of Equipment andInstruments
Ion Source・Realignment is not necessary. This is also
confirmed through the calculation of RFQbeam.
・Installation of the plasma production room,and wiring and plumbing work have beenconducted.

Vacuum Chambers

・Realignment of the chambers of DTLand SDTL is continued.
・Misalignment of each axis of threechambers of DTL appeared to be within
0.1 mm.

Cooling Facility, etc.

・Restoration work of theplumbing and pumping system
is continued.
・CRYO pumps were removed
and inspected.

Status of 3 GeV Synchrotron (RCS) Facility in July-1
Restoring the powersource yard and thebuilding has a first priority.

・Stages for the equipment
to receive high voltage
power were jacked up tomaintain their level.
・After confirming its
soundness, continuous
current tests have started.

・Restoration work of outsideplumbing was completed.

Status of 3 GeV Synchrotron (RCS) Facility in July-2
Primarily restoration work of the condenser and transformer has been conducted.

Placing
concrete blocks
to maintainheight of thecondenser.

The tilted condenser was straightened.

Status of 50 GeV Synchrotron (MR) Facility in July・Water Leakages in Tunnels
Leakages in ceiling and walls of the main tunnel were fixed. And then, repairing work ofthe floor and 3-50BT and sub- tunnels has started.

・Leveling of the Main Tunnel
Leveling of reference points of the tunnel is conducted by two teams through the middleof August. Magnets will be aligned after that.

・Revamping Work of Equipment
Revamping work of equipment, including improvement of shielding around the ring
collimator area, has started. The lower photos show the work for removing beam pipes.

Restoration work of Building
Restoration work of plumbing was conducted. Water
supplying system has been restored.
Repairing floors and walls of 3NBT building and a tunnel
are in progress.
Replacing pipes for waterand compressed air.

All pipes mounted on walls were removedprior to restoration work.

Floor in a tunnel
has been repaired.

Damaged wallboards werereplaced.

South Side of the 2ndMachine Bldg.

・Switch Yard
Leveling and lining are in progress. After beamlevel from 50GeV synchrotron is fixed, thelevel of slope part will be adjusted to the beam.
・Hadron Hall
Inner electrodes of the 1st separator of K1.8
were investigated for confirming their levelingand spacing, and were placed in a correct
position. The next step is to test them underan operating condition.

・Ground/road conditions around the target
station have been almost restored.
・Crane at a bring-in entrance has got back inoperation. No damages were found inshielding blocks and gaskets.

・Preparing for the realignment of normal
conductivity magnets. The beam-monitor and –pipes were removed.

Current Status around the Target Station

・Regular maintenance and inspection of thecooling system of the superconducting
magnets have been also conducted.
・Rehearsal for moving the 3rd horn for its
inspection has been conducted.
・The 1st and 2nd horns will be tested for theirnormality under an operating condition in thenear future.
