Microscopy Cryostat System RYO Compact - lightweight and portable, easily inte- Ef cient - lower cryogen consumption, Flexible - operates in any orientation Optimized - adjustable close working distance genic Workstation Variable temperature - Versatile - Use either liquid helium or nitrogen - ‘push-or-pull’ operation RYO The RC102-CFM is a sample in vacuum cryostat. The sample holder is located in vacuum. A flow of liquid helium or nitrogen cools the sample, which can be adjusted away from or very close to the window using vari-height thread in sample holders. For high rigidity and stabil-ity, the sample is supported by opposing tension supports.Liquid cryogen is delivered to the sample mount through the vacuum insulated transfer line. An adjustable needle valve provides  ow rate control. Connect the heater on the sample mount to the temperature controller for automatic variable temperature operation. e WORKSTATION can be operated in any orientation.  e standard system includes a six (6) foot (8 foot optional)  exible transfer line with a 50 inch long (60 inch optional) storage dewar leg. e typical setup consists of the RC102-CFM cryostat, a liquid helium (or nitrogen) storage dewar, helium gas cylinder with pressure regulator and a vacuum pump. A stainless steel  exible transfer line is supplied with the system. e transfer line leg inserts into the liquid cryogen. A small pressure is used to transfer the liquid out of the storage dewar, through the transfer line and directly to near the sample mount. Alternately, a small vacuum pump can be used to pull the liquid helium from the storage dewar. A  ow control valve regulates the cryogen  ow. Pressure inside the storage dewar cryogen reservoir can be adjusted using a helium gas cylinder. An activated charcoal cryopump built into the transfer leg will automatically pump when inserted into liquid helium or low pressure nitrogen dewar, maintaining excellent vacuum during extended periods of operation.  e transfer line quick disconnects to and from the microscopy WORKSTATION.Electrical connections to the sample are made through the o-ring sealed ports located on the instrumentation housing. A spare port is provided for future requirements. For safety, the shroud and transfer line are protected against overpressure by pressure reliefs. e evacuation valve for the transfer system is located above the valve control knob.  e evacuation valve for the sample region is on the instrumentation housing.  e vacuums are completely independent.Windows at 0 and 180 degrees provide optical access. For re ection, the total angle of acceptance is 130 - 152 degrees, depending on sample position. For transmittance, the angle used quartz, 1.5 mm thick (0.5 mm thick option is available); suprasil, ZnSe and other window materials can be selected.  e standard clear view aperture is 24 mm diameter (13 mm for 0.5 mm thick windows).  e adjustable holder allows the sample to be moved right up to the window. Samples can be mounted through the radiation shield opening or half the radiation shield is removable to allow full access.Variable temperature is automated using an electronic temperature controller. A heater is imbedded in the sample holder. Set the temperature into the con-troller and obtain the desired temperature. Operation below 4K is achieved by reducing the  ow pressure by pumping on the helium vent.

Liquid cryogen helium or nitrogen can be drawn from the main reservoir into the sample region by either: PushingŽ - A small pressure in the storage dewar pushes the cryogen from the stor-age dewar into the transfer line to the sample mount.Or,PullingŽ - Sucking liquid from the main storage dewar to the cold  nger by using a small pump.  e liquid helium is drawn from the main reservoir of the storage dewar into the sample mount using a small diaphragm (gas  ow) pump, while maintaining the storage dewar near one atmosphere.€ 3.2 K to 325 K operating temperature range • Operates with either LHe or LN• Operates in Push or Pull modes Pull - pump = ‘pull’ • (2) 0.93 inch [23.6 mm] diameter windows(2) 0.93 inch [23.6 mm] diameter windows0.020 inch [0.5 mm] thick window optional• Windows top and bottom • Adjustable sample holder• 50 ohm heater installed on sample mount• 19-pin hermetic electrical feedthrough• Spare blank feedthrough port• NW25 vapor pumping port & vacuum valve• Flexible stainless steel transfer line ow control valve• Silicon diode temperature sensor installed• 30 mm thin• Solid - internal support spacer RYO What is a NOMOVE?The sample holder is supported radially with opposite and equal support forces. The supports are rigid and anchored directly to the outer vacuum jacket. There is no physical support to the sample holder through the cold finger and radiation shield,. The sample is physically de-coupled from the internal thermally contracting (moving) cold components. Thermal contraction is toward the center of the sample, resulting in the lowest movement design. The supports are designed to operate in the elastic region. Supports are rigid and under tension. Movement toward or away from the window is virtually zero because there is no support component in this z-direction.Lowest Vibration t your setup. ciency, excellent RYO holders allow for quick sample change, adjustable distances and selectable diameters and apertures. ow of liquid helium or nitrogen cools the sample, which justed for varying sample thicknesses.
