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.

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.

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.

ANSYS calculation (EMU TDR, page C7) shows a distortion in Z-directionof endcap disks (outer edges) for about 6 mm that is in good agreementwith 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.
