19. Task L, Oct.9-10, 2006Valery Andreev, UCLA19 Laser Operation: Safety DCOPS red cross hair laser, Class 3A: - = 635 nm - P = 10 mW Laser Displacement sensor, infrared, Class 3B: - Z4M –W100 Omtron -  = 780 nm - P = 3 mW max To comply with CMS safety regulations we have installed laser warning signs and additional safety shields for EMU system. We have also provided a logic triggered relay system to operate Laser warning lights when laser operation occurs. Now safety clearance for SLM laser operation and laser displacement sensor has been approved. Date: Wed, 24 May 2006 15:41:51 +0200 From: Roland Magnier To: Valery Andreev Cc: Christoph Schaefer, Thomas Sobrier, Emilie Freret Subject: Use of crossed line lasers for alignment of endcaps discs in CMS Hello Valery, As discussed at the test place (SX5) this afternoon, we give you our approbation for the use of these lasers, which, when used with the LO 45 optical device, as it is the case, are of class 2. For the class 2, the eyes are naturally protected with the blink relex. The plate used in the vicinity of the lasers is a good protection anyway. Best regards.

21. DCOPS Readout SLM DCOPS (Digital CCD Optical Position Sensor) The Endcap Muon Alignment System utilizes an optical sensor composed of four linear CCDs (2048 pixels) in a picture frame configuration to sense the position of two crossed lines of laser light passing through the sensor.

22. Analog Sensor Readout The analog readout is used for R, Z, proximity, and temperature sensors and for inclinometers. The resulting voltages produced by these sensors are measured by the ELMB mounted at the analog readout unit and connected to CAN bus. To provide a communication between the analog sensors and the readout unit, the analog interface boards are used. UCLA contribution: X. Yang, slow control program S. Guragain (Florida Tech) X.

25. Task L, Oct.9-10, 2006Valery Andreev, UCLA25 MTCC: alignment, disk bending ANSYS calculation (EMU TDR, page C7) shows a distortion in Z-direction of endcap disks (outer edges) for about 6 mm that is in good agreement with Z1 laser displacement sensor data for upper point 2 but for lower point 5 and 6 the disk bend deformations are less than predicted. No linear dependence verses magnetic field was observed 6 laser displacement sensors were mounted on theYE+1 disk but only 3 MABs on YB2. YE+1 O. Prokofiev, FNAL

27. Alignment: Summary and Plans We’ve had a good progress for the last 6 months:  Completing alignment hardware installation for the plus disks  Completing digital and analog readout software  Starting a system commissioning  Starting data taken and on-line data analysis Most critical items on to-do list:  Continue installation and commissioning  Running system with good data quality raw sensor data  Pushing raw sensor data through PVSS into root file  Arranging on-line data analysis  Getting final COCOA geometry in place  Making survey and CMM data useful

28. Task L, Oct.9-10, 2006Valery Andreev, UCLA28 Underground commissioning Lowering of disks from November 2006 to June 2007 The commissioning to begin as soon as we are underground The schedule is driven by availability of services underground Looking forward to beam next year !
