PN OPERATIONS · PN new BRAT of 24 Kbps is now permanent, selected from the T/L or manually reconfigured if required. · RGS 2 in SETUP from 1207 to 1210, due to analysis of NCR-113 (no science produce, anomaly found correlated to temperature of electronics). Impact on the gain of PN, due to electronics cool down. · TC failure in PN F 0096 in rev #1214, one quadrant not responding to it and remaining in ROM version. Detected through consistency among all EPEA SW versions. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 7

PN OPERATIONS · Special Tests for PN · PN Timing with modified threshold during the NRCO-63 in Omega Centauri, rev. #1227 (threshold lowered by 4 ADU to 548 without offset calculation). · Future tests for November 2006 – Lower threshold by 4 ADU in LW during RCO of OM. Offsets to be calculated with or without new value ? ? ? – NRCO-57 repeat, source PKS 2155 -304, SW with offsets in closed FW set to Thin-Medium-Thick final Offsets in Thick XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 8

PN OPERATIONS · PN LCL failure in rev 1201, 30/06/06 · SEU opening of LCL for EPIC PN Branch A, causing loss of power to the instrument. · Thermal situation under control thanks to CDMU J CSF function and good operator and engineering responses. · MOS thermal impact due to the use of redundant heaters.

Slow Slew Survey SLEW SURVEY XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 17

Slow Slew Survey – Overview · New Operating Mode proposed to increase flexibility and use of XMM-Newton with respect to future Science Operations. – Full Sky Survey taking ~190 revolutions – Galactic Plane Survey taking ~15 revolutions · PN designated as prime instrument and to be used in Full Frame (Medium). · MOS to use new 3 x 3 binning mode (Medium). · RGS using CCD 5 (Oxygen Line) and CCD 9 (Soft Proton Detection) with polling sequence (55555559). XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 18

Slow Slew Survey – Overview (cont) · OM requires new High Time Resolution mode (RTRD) to be developed. · Feasibility testing at both Spacecraft and MOC/SOC systems level had to be completed by end September 2006. · Complete revolution (1242) dedicated for first Survey across the Galactic Centre. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 19

Slow Slew Survey – Preparation · MOC perform testing of slew speeds at both 20 deg/h and 30 deg/h. The later is chosen to be used during rev 1242. · PN Offset calculation repetition rate increased to 100 to gain cleaner pixel by pixel offset values. Testing indicates no problems. Database definitions already present hence no further work required. · MOS 3 x 3 binning mode implemented with its reduced frame time of 0. 4 s in comparison to Full frame (2. 7 s). Initial testing performed manually during rev 1210, with relevant definitions consequently being applied in the database and re-tested during rev 1228. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 20

Slow Slew Survey – Preparation (cont) · Updated Database released to support rev 1242 Survey. · Due to no proposals being available for Slew Survey, and consequently no targets, the planning could not be performed using the Proposal Handling System. This meant that a high level of manual intervention was required to produce the POS/ICP. · Rules and Constraints file used to integrate database components into planning cycle. Thereby, offering full flexibility and by passing the need for Activities. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 21

Slow Slew Survey – MOS 3 x 3 Binning · First test during rev 1210 (CALCLOSED) was performed only on MOS-1, without any Bright Pixel masking and theoretical offset tables (TC’s manually modified). The test being performed with both 0. 4 s and 0. 5 s integration times. · Second test, to verify database entries, was performed during rev 1228 (CALCLOSED) on both MOS-1 and MOS-2. Bright Pixel Tables were derived from the 1 x 1 Sequences and Offsets based on results seen during rev 1210. No further changes were necessary for rev 1242. · Clock sequences used were the same as for 3 x 3 diagnostic. · Bandwidth remained at roughly 6 kb/s during above testing. Therefore, no appreciable increase compared to 1 x 1 (CALCLOSED). XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 22

View on right showing all CCDs in comparison to the zoomed view on the left. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 23

Slow Slew Survey – Rev 1242 · Survey consisted of 16 Open Loop slews across the Galactic Centre each lasting around 1. 5 hours at a rate of 30 deg/h with each leg being separated by 15 arcmin. A Closed Loop Slew (~17 mins) then being used to move from the end of one OLS to the start of the next. · In order to keep filter wheel movements to a minimum EPICs remained in an Medium position during all slews. · To ensure EPIC safety against radiation, RGS remained observing during both Open and Closed Loop slews thereby providing soft proton detection at all times. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 24

Slow Slew Survey – Rev 1242 (cont) · MOS/PN sent to idle at end of each Open Loop Slew (FW remained in Medium) This ensured correct termination of data products for each leg. · During the Closed Loop Slew PN down-linked discarded lines. · RGS used as originally foreseen. · OM used in Image+Fast (UVM 2) with reduced window size (2 windows of 22 x 23). XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 25

Slow Slew Survey – Future Activities · Super ED’s required to rejoin instruments during an Open Loop Slew, thereby removing the current constraint of rejoining at the start of the next leg (worse case loss of 1. 5 hours). · Incorporate inputs from calibration team for 3 x 3 mode (new offsets/Bright Pixel Tables) into Database (i. e. fully commission mode). · PN observations will be extended into the Closed Loop Slews by sacrificing down-link of discarded lines. Requires new ED. · Implement strategy for reduction of manual activities required for POS/ICP Generation. XMM-Newton Guillermo Buenadicha / Neil Cheek SOC Operations Support Group Page 26
