  1. Report of activities in T1049 (M6-FTBF) • Introduction • Test beam set-up • Preliminary results • Conclusions

  2. ATLAS Phase I upgrade • To reduce μ trigger rate in forward direction, need accurate vector (>1mrad) in front of magnet. • Groups from Canada, Chile, China and Israel developed the sTGC that have achieved good position (~70μm) resolution and high efficiency in high background environment • Two type of detectors to be used in ATLAS Phase I New Small Wheel (NSW) upgrade (sTGC & MicroMegas). • New method to produce large (2X1.2m²) multi-layer PCB’s had to be developed that can be placed with respect t each other with a precision of 40μm. • First final size quadruplet of such a detector has been tested at FERMILAB (T1049 in M6-FTBF between 9/5 to 20/5).

  3. Test beam set-up • Sandwich the sTGC quadruplet prototype between 2 pixel telescopes (EUDET)

  4. Some taste of on-line results Residuals on individual layers range between 50-100μm Without correcting for binning effects

  5. Conclusions • Encouraging first results with a large detector and VERY PRELIMINARY electronics with 512 fast electronic channels. • Very good collaboration between Canadian and Israeli groups that managed to come to FNAL. • Excellent support from the FNAL crew headed by Aria (nice to be at FNAL after 40 years)
