Installation

This section covers unpacking and installing your new nanowire detector system.

1. If a front cover is attached (refer to Figure 7), to protect the optical, electrical, communication, and One-Button user interfaces, loosen (do not remove) the bolts securing it using a 4mm hex key, lift the cover slightly, pull it off from the front of the system, then re-tighten the bolts.

2. Review the voltage and frequency specification listed on the QR code sticker on the back of the unit and confirm the availability of a suitable outlet.

3. Plug the power cable into back of the Opus One Portable unit and plug the other end into the electrical outlet.

4. With the electronics switched on, the control button will light up green, and the small status LED should turn orange if the unit is not connected via USB. Refer to Figure 8 on the next page for LED and switch layout.

Before unpacking your Opus One unit, ready the compressor unit. Carefully consider the placeent of the compressor and Opus One. Refer to Figure 4 or Figure 5 for layout.

1. Determine compressor and high-pressure helium location appropriate for proper proximity to your water and power connections.

   NOTE

   Because of the polarization sensitivity of the nanowire devices, it is important to minimize uncontrolled polarization drift between your source and the detector unit. Polarization drift can be made worse with long optical fibers, fibers that continually change position (e.g., due to vibration or air currents), or fibers that change temperature.

2. Determine the Opus One unit location appropriate for your source of photons, ensuring
   that the helium lines can move freely and will not be under tension. Minimize the distance
   between your optical source and the detector unit.

   NOTE

   If you have stand alone electronics, it is intended to be operated either directly above or below the Opus One Standard unit to minimize the introduction of noise between the electronics and the Opus One unit.

1. Establish the proper electrical and water connections to the compressor according to documentation provided separately by the compressor manufacturer. Be sure to comply with all manufacturer recommendations and local laws, codes, and building recommendations.

2. Perform any recommended compressor run testing. See provided compressor manufacturer documentation.

3. After any required compressor run testing, install the high-pressure helium lines onto the compressor SUPPLY and RETURN connections and the drive cable, as described in the compressor manufacturer documentation.

1. Lift and position the Opus One according to the following guidelines. Avoid lifting by any valve, port, electrical, or tubing connections. As long as you avoid the tubing lines, you may lift by the central solid aluminum block at the rear of the unit, as shown in Figure 9.

2. Carefully remove the Opus One unit from its packaging. Note that the unit has a significant fraction of its weight toward the back. It is critical that the unit remain horizontal.

3. Remove any protective wrapping around the Opus One unit and on the front panel.

4. For rack-mount operation, it is essential to support both the front and back of the system using a shelf which is rated for at least 500 lb or 225 kg, although your Opus One unit only weighs about 50 pounds, to account for dynamic loads such as those that may occur during seismic activity or other unforeseen loading conditions. Contact Quantum Opus support for guidance on the selection of an appropriate shelf mount.

5. If desired, apply the provided adhesive feet near the corners of the bottom panel of the Opus One.

   

   Figure 9: Rear view of the Opus One Integrated unit with built in vacuum pump showing a suggested lift point for installation.

6. Ensure any temporary or final location is chosen such that, after the high-pressure helium lines are connected, strain on the high-pressure helium connections at the rear of the unit is minimized.

7. The pressurized helium lines must be connected in the following order.

   1. Ensure the SUPPLY and RETURN lines are already connected to the compressor and properly labeled SUPPLY and RETURN.

   2. If (optional) pressurized right-angle adapters are to be used, contact Quantum Opus for the proper installation procedure.

      WARNING

      Using the improper method of connecting the helium lines, connecting in the improper order, or erroneously interchanging the RETURN and SUPPLY lines may result in permanent damage to the tubing lines or necessitate service to the Opus One unit. Adhere to the following procedures carefully.

   3. First, using the proper “three-wrench” procedure as illustrated on page 26 of the Sumitomo Cryocooler Operations Manual (available in the Support section of our website), connect the “RETURN” high-pressure helium line to the “RETURN” connector on the rear of the Opus One unit.

   4. Second, again using the proper “three-wrench” procedure, connect the “SUPPLY” high-pressure helium line to the “SUPPLY” connector on the rear of the Opus One unit.

   5. Connect the provided electrical cold head drive cable between the compressor and the
      Opus One unit. Refer to Figure 10 and Figure 11 to identify the correct cable.

Figure 10: Three Meter Example of Air Compressor Electrical Cold Head Drive Cable.

Figure 11: Three Meter Example of Water Compressor Electrical Cold Head Drive Cable.

Opus One Integrated units have integrated compressor control relays. In addition to connecting the cable, the compressor switches must be set properly for remote operation as follows. The same is true for the remotely operated vacuum pump. Refer to Figure 13 on the next page to help you locate the DB-9 Connector on the Opus One integrated unit for the compressor control.
