TR-SES-200 High Resolution VUV/UV Transmission and Reflection Evaluation System Manual
System Overview The Resonance Ltd. Transmission and Reflection Evaluation System is designed to deliver vacuum-ultraviolet (VUV) to ultraviolet (UV) radiation to a target sample and measure the reflectance, transmission or fluorescence of the target. The system includes a deuterium lamp emitting from 115 nm to 400 nm, a 200 mm focal length vacuum monochromator with a PC controlled motor drive, a Hamamatsu R8486 photomultiplier tube (PMT) capable of detecting from 115 to 320 nm, LabviewTM software and controlling electronics.

TR-SES-200 Main System Parts
Quick Setup and Operational Checkout Hardare Setup 1.  Unpack System 2.  Attach the TR-SES-200 to the pump (either back or bottom 4.5 inch CF can be used). Figure 3: Vacuum hose and elbow 3.  Open the sample wheel door Figure 4: System with Sample wheel door open 4.  Carefully remove PMT wheel locking tie 5.  Place the sample wheel on the spindle making sure it sits flat by aligning the spindle pin to the alignment hole on the      wheel.  Tighten the locking nut onto the spindle. Figure 7: Sample wheel placement (shown prior to application of black paint) 6.  Close the sample wheel door making sure the vacuum seal o-ring sits flat inside the goove of the door.  Fasten the               door bolts until there is compression of the o-ring. Figure 8: Vacuum seal o-ring seated in door 8.  Attach the lamp to the entrance slit flange of the monochromator with the screws and viton gasket provided.  Tighten      the screws until the gasket compresses and the lamp flange is touching the entrance slit flange. 9.  Plug in the main electronics to box to AC power. 10.  Plug in the two electronic D style cables and the two plastic connectors to the Main Electronics case and vacuum        chamber.  Follow the color code to ensure the cables are plugged into the right connectors. Figure 11: Electronics cas connectors 11.  Plug in PC to AC power. 12.  Attach the Camera and LED mount to the side view port by sliding the case on until it clicks in.  Plug in the        corresponding USB and LED cables to the PC/electronics box. 13.  Plug in USB cable between the Display and the PC/electronics box. 14.  Turn PC on by pushing the PC On/Off button on front panel.  The PC Power LED on the Main Electronics box should        come on (if not, check cables). Figure 12: Power indicator LEDs on electronics case 15.  Turn on system elctronics.  The Lamp, PMT and Servos green LEDs on the Main Electronics box should come on.        Note: The PC may operate independently from the TR-SES-200 system electronics.  When not using the        transmissometer for an extended period of time it is recommended to turn off the system electronics.  Keep in        mind the lamp has a warm-period. 16.  Open the VUV Spectrophotometer software by double clicking the TR-SES-200 icon on the desktop. 17.  The indicator lights at the top of the screen should glow green after a few seconds. 18.  Make sure there is nothing obstructing any of the stages from rotating. 19.  Observe that the fan turns on when system electronics is on. Figure 16: Lamp Mounted to VM200 20.  Allow approximately 20 minutes for the lamp to warm up and stabilize. 21.  Meanwhile, carefully close the PMT door and bolt shut until the O-ring compresses. 22.  Set aperture to Open Aperture with software. 23.  Carefully close the sample holder door and bolt shut until the O-ring compresses. 24.  Open slits (2) to 800 microns. 25.  In the program, go to the “PMT Rotation” tab and set the desired angle to 0 degrees.  The PMT rotation motor will make        a sound and the displayed PMT angle will start changing.  Wait until the PMT reaches zero position. 26.  Go to the “Sample Rotation” tab and set wheel rotation to a vacant sample location. 27.  On the “Spectrometer” tab, set the desired Wavelength to 230nm and press the “Scan” button in the bottom left corner. 28.  Click the PMT button to turn on the photomultiplier tube (located in the lower right-hand corner of screen).  Set the        “PMT Gain” (adjustable via slider or value input box) to an initial low value and increase accordingly to the PMT signal        value so as to not saturate the signal.  You should observe the numeric value in the “PMT Signal” box increase while        adjusting the PMT gain to get a peak value below the maximum signal.  If the PMT is exposed to a large signal while        the voltage is set high, there is a possibility of damaging the detector! Figure 20: PMT gain and signal location 29.  After the lamp has been running for 20 minutes, scan the spectrum from 170 to 310nm at a resolution of 0.1nm.  One        should see the UV portion of the D2 lamp spectrum which peaks at 230nm.
