Infrastucture and Schedule

April 6th 2009 Olympus Meeting at DESY, F.Brinker 2

Detector power supply

• A 10kV to 480V transformer is available and will be placed outside the experimental hall

• The foundation has to be prepared• The 7000 A power supply from Petra has to be installed

in the hall • The cabling to the transformer (10kV), to the power

supply (2500A, 480V DC) and to the detector (7000A, 225V DC) has to done ( ~ 9 km cable in total )

April 6th 2009 Olympus Meeting at DESY, F.Brinker 3

Water cooling

• A cooling water circuit for about 1.6 MW for the toroid has to be installed

• The capacity of the cooling tower is sufficient• the place for the heat exchanger and the water pump is

available near water supplies from the cooling tower• A heat exchanger and a water pump can be reused from

Hera/Zeus• The tubes, regulation and electronics will be new• Cooling for the moved cavities is still available, the last

few meters are missing• Cold water for air conditioning is available, tubes have to

be laid

Polarity switches• There are 46 main magnet power supplies at DORIS and

the transport line• 12 of those are already replaced by bipolar devices• 10 devices with currents below 270A can be modified

with polarity switches from HERA• The remaining 24 devices need new polarity switches,

14 devices for 400A and 10 devices for 800A• Cabinets, controls and cabling have to be done

Kicker pulser

• The extraction/injection elements at DESY and DORIS have to be bipolar

• The Septa can be modified accordingly• The Kicker ( 2 DORIS + 1 DESY ) need new power

supplies, which can be build at DESY ( spare parts? )

April 6th 2009 Olympus Meeting at DESY, F.Brinker 7

Preparation of the experimental hall

• Parts of the hall are in use as store room, the parts here have to be removed

• Another part is used for an DESY exhibition, these objects will be removed and partly find a new home in HERA hall west

• The ARGUS detector has to be disassembled and removed

This work can start soon and should be finished by the end of this year

April 6th 2009 Olympus Meeting at DESY, F.Brinker 8

Modification RF-lab

• An RF laboratory for testing of Tesla cavities is placed on the outside of the DORIS ring

• A rectangular region of 2.5 x 9.5 m has to be cut out – Install dust cover– Remove walls – Cut ceiling and floor– Build new walls– Change installations ( crane, electricity, water etc.)

This work can start in summer 2010, when the ongoing work in the laboratory is finished (earlier, if possible)

April 6th 2009 Olympus Meeting at DESY, F.Brinker 9

Modification of the IP region (1. shut down )

• Move signal cables from IP region ( can be done in advance )

• Remove interlock installations• Remove shielding blocks• Remove accelerator components

– Cavities, vacuum chambers– 4 quadrupoles– Girders

• Install dust cover• Demolition work on parts of concrete

April 6th 2009 Olympus Meeting at DESY, F.Brinker 10

Modification of the IP region

• Build up new shielding• Install new girders/support for experiment vacuum• Put in 6 new quadrupoles• Install vacuum system, including target chamber and

new vacuum valves• Install cavities at the new position• Cabling, water connections• Install modified interlock system• Surveying

April 6th 2009 Olympus Meeting at DESY, F.Brinker 12

Installation of Olympus ( 2. shut down)

• Remove part of shielding• Remove vacuum system between valves• Roll in the detector• Install vacuum chambers• Connect cooling water and electrical power• Rebuild shielding• Surveying• Interlock tests
