Department of Physics

University of Jyväskylä,Finland

ECPM 2006, Nice

Outline


Statistics


New plans


New diagnostic tools


Estimated use for 2006 is 7500 hours


Very little time for maintenance


Practically no time for machine development


30 different isotopes


1/3 protons


mainly for proton induced fission and 123
-
I production


Cocktails for space electronic testing (ESA)

New cyclotron


30 MeV H
-

cyclotron MCC30/15


from NIIEFA (Efremov Institute, St. Petersburg)


as a partial compensation of former Soviet Union dept
to Finland (Inter
-
governmental agreement between
Finland and Russia, August 15, 2006)


Full system with two beam lines


beams for IGISOL (p
-
induced fission) and MAP Medical
Technologies (123
-
I)


provision for second extraction


e.g. 18

Diagnostic tools


Beam impurity measurement


Rutherford scattering


2009


Infrared camera


Power supply checking at one glance


hot spots


poor contacts in power supplies


too hot components


cold spots


dead components (transistor bank)


dead fans (power supply racks)


insufficient cooling


cooling circuit blocking


HV leaks


warm insulator


Poor contact


higher resistance


hot

Hot components

See the temperature rise in a double
pancake

Note to IR measurement


Don’t measure reflected IR


IR reflects from metal surfaces


use (black) tape on surface if possible


learn to use the camera and interpret the
IR picture correctly


Nowadays cheap hand
-
held cameras
available


From 5000


(up to 50’000


or more)


No LN2 needed for cooling
