1 17D244 Dipole: (to be measured)
1 41CDM30 corrector for Ring Injection dump
Four test stands developed to handle magnets as small as DTL PMQ and as large as any size.
Two different kinds of search coils to detect magnetic flux:
One translational coil for HEBT dipoles 8D533 and 8D406.
Seven rotational coils of the Halbach type for all other magnets
Three electronic systems including digital integrator, digital tesla meter, digital voltage meter, power supplies, current sensors, etc.
Labview software for test control and on-line data processing.
A H-shaped dipole with curved pole tips;
Weigh 46000 LB;
A rotating search coil of 3.8 m long with support at two ends & middle point has been developed to map the dipole in the RTBT tunnel.
The B*L along a curved beam trajectory has to be reconstructed based on test results.
