Entry number 379
This entry is a followup to: 377
Followups:
- 386 09/27/03 11:13 horn BQ1/pHMS and BQ2/pHMS
- 389 10/04/03 11:01 horn Ratio of IQ3_read/IQ3_set
- 390 10/04/03 11:27 horn Ratio of I_read/I_set for Q1 and Q2 respectively
Fig 1 depicts the ratio of the magnetic field of Q3 vs. HMS momentum for an extended range of HMS momentum compared to entry #377.
Including the data at higher momentum suggests a plateau at BQ3/pHMS=1.003, which implies a deviation of the linear behavior of the curve below p=-3.5. This variation of the field-to-momentum ratio with momentum could suggest a residual current offset in Q3, which is, however, not as pronounced as seen in the data from 1998.
The data is divided into two subsets by date, which is motivated by the possibility that the true zero of the hall probes may change with time.
