1. Ziptrack Apparatus ● Ziptrack beam rests on two manipulators (brown and orange things) ● Cart sits on silver beam which holds the Hall probe ● Cart moves along the beam (z), manipulators move the beam in (x,y) 1 z z z y x Ben Freemire, Terry Hart, 01/14/09

2. Current Plotting Dialogue 2 ● Input raw data from Hall probe ● Plot dialogue developed, shown at left ● Plot B x, B y, B z in (x,y), (x,z), (y,z) planes ● Specify number bins in plot, output plot type ● Plots saved as ROOT files, can be.ps or.eps files ● Physics checks (Maxwell) under development ● Documentation to be written ● Lots of options, flexibility z z z y x Ben Freemire, Terry Hart, 01/14/09

3. 2D Plots from Test Dipole Magnet 3 ● Dipole field along x ● z along Ziptrack beam, beam with Senis Hall probe shifts along (x,y) – (see previous slides) ● 208 counts/gauss ● Dipole field B x – -350,000 counts ~ -0.175 T ● Measurements are reasonable Ben Freemire, Terry Hart, 01/14/09

4. Further Goals and Schedule ● Debug plotting features ● Implement Maxwell checks (  x B,   B = 0). – Doug Jensen has Fortran routines to be used as a basis ● Check consistency by comparing test magnet data taken from probes for MICE (NIKHEF) and MIPP (Senis) ● Ziptrack MIPP’s Jolly Green Giant ready mid-February ● Solenoid 2 scheduled to ship late February 4 Ben Freemire, Terry Hart, 01/14/09
