This project focuses on the Ziptrack apparatus, which involves a silver beam supported by two manipulators (one brown and one orange) that allow a cart with a Hall probe to move in the z-direction. Key tasks include developing a dialogue for inputting and plotting raw data from the Hall probe across various planes (Bx, By, Bz) and saving the plots as ROOT files. The goal is to implement comprehensive Maxwell checks and improve the plotting features, with notable developments planned for mid to late February.

1 Ziptrack Apparatus y • 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) x z z z Ben Freemire, Terry Hart, 01/14/09
2 Current Plotting Dialogue y x z z z • Input raw data from Hall probe • Plot dialogue developed, shown at left • Plot Bx, By, Bz 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 Ben Freemire, Terry Hart, 01/14/09
3 2D Plots from Test Dipole Magnet • 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 Bx • -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 Ben Freemire, Terry Hart, 01/14/09
