High quality muon detection for the SSC

PDF Version Also Available for Download.

Description

We present an alternative approach for muon detection at the SSC based on a high field magnet (B = 5 Tesla) of ``moderate`` dimensions (radius = 3.5 m; overall length = 15 meters). A precision determination of a muon`s momentum is made using a point-slope method, where the point is the interaction point and the slope is the direction of the muon`s track as it exits the magnet coil. Momentum resolutions on the order of {Delta}p{sub t}/p{sub t} {approx_equal} 4% are possible over large solid angles for muon momenta as high as 1 TeV with rather modest alignment ({approximately} 200,{mu}m) ... continued below

Description

We present an alternative approach for muon detection at the SSC based on a high field magnet (B = 5 Tesla) of ``moderate`` dimensions (radius = 3.5 m; overall length = 15 meters). A precision determination of a muon`s momentum is made using a point-slope method, where the point is the interaction point and the slope is the direction of the muon`s track as it exits the magnet coil. Momentum resolutions on the order of {Delta}p{sub t}/p{sub t} {approx_equal} 4% are possible over large solid angles for muon momenta as high as 1 TeV with rather modest alignment ({approximately} 200,{mu}m) tolerances, with standard drift chamber resolutions ({approximately} 100{mu}m), and with no reliance on the performance of an inner tracking system. Robustness is provided by additional momentum measurements in the inner tracker and in a solid iron spectrometer utilizing the magnet`s return yoke. The total cost of the system, including proper magnetic shielding for the magnet and a forward-backward iron-core toroid muon detection system with {Delta}p/p {approx_equal} 9%, is comparable to that of the low-field L*/GEM approach that does not provide a magnetic flux return nor a forward-backward iron system. The magnet leaves the same amount of space for inner detector items as does the large, low-field L*-type system, while providing a substantially higher magnetic field in the inner tracking volume.
