1 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM Status of data retrieval (SSS and S4 tested in SM18). Data retrieval : goals, agenda. Procedure of data treatment and validation Status of the data treatment (20/02/07).

2 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM Number of quadrupoles to be treated. MQ: 28 MQ (transfer function, multipoles). MQM : 4 MQM (transfer function, multipoles)  The other MQM were measured in Block 4 and treated by W.Venturini. MQY : 12 MQY (transfer function, multipoles)  MQY measured in Block 4 will be treated by W.Venturini. MQTL (Q6): 1 measured completely in SM18. 45 magnets to be treated in total.

3 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM What we will get after the retrieval. 4 reference tables corrected and entered in the SMA web site.  Transfer function: TF for currents between injection and nominal in ramp up and ramp down (systematic correction with SSW measurements)  Integrated harmonics: Integrated strength and multipoles between injection and nominal in ramp up and ramp down.  Integrated components: Geometric, saturation, magnetization, hysteresis, decay (when it is measured).  Variation of the b 2 and multipoles with time during the reference machine cycle (format table integral_harmonic) Agenda  For MQ in arc SSS : ready end of February.  For MQY and MQM : ready end of March.

4 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM Cleaning procedure. Re-analysis of the raw data coming from machine cycle and load-line. Transfer function  Check/correct the offset based on SSW measurements  Correct jumps in transfer function along the loadline in particular around 2000-3000 A  Add the ramp down YF=f(I). Angles  Introduction of the Mag_fid angle measured with the SSW (table provided by Marco Buzio) Harmonics  Add the multipoles as a function of the current (ramp up and down) Multipoles components  Check of the components  Ramp rate effect added when measured  Decay file prepared (variation of the b 2 and multipoles with the current for the reference cycle). Final checks  Creation of a log file including offsets, angles, comments.

5 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM Transfer function correction :extreme case. Raw data Strength correction based on SSW cross-check + jump at low current corrected. Correction confirmed by another measurement with re-calibrated amplifiers Criteria : Correction performed when the jump is higher than 1 unit.

6 FIDEL meeting 22/02/07 - Stephane Sanfilippo AT-MTM Status of the MQ, MQM, MQY treatment.  MQ: 16 treated/ 28 the 20/02/07.  No MQM and MQY for the moment.  Second run of checking is needed at the end.
