1
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 )

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? )

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

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
