Page 3: Precautions
High Voltage The Mini-X-OEM is designed to generate voltages up to 50 kV. The high voltage system is fully shielded inside the Mini-X-OEM enclosure. DO NOT ATTEMPT TO ACCESS OR MODIFY THE HIGH VOLTAGE SYSTEM. -
Page 4: Heat And Temperature
The ambient temperature surrounding the X-ray tube must not exceed 50 C. Improper cooling is the single highest cause of X-ray tube failures and is not covered under the Mini-X-OEM Warranty. It is the user’s responsibility to provide an adequate cooling system for the Mini-X-OEM. -
Page 5: Options And Variations
Mini-X-OEM User Manual Rev D2 The Mini-X-OEM has been designed to simplify the XRF process by providing a grounded anode, variable current and voltage controlled via USB and ease of operation. It features a 50 kV/80 µA power supply, a gold (Au), silver (Ag), rhodium (Rh), or tungsten (W) transmission target, and a beryllium end window. - Page 6 Figure 2. Mini-X Isopower. The current and voltage must be set in accordance with this curve or the Mini- X may be severely damaged. Damage of this kind is not covered under warranty. Amptek’s control software limits the power to this curve. If one commands the system to a power exceeding the power limit, the software will use the commanded HV and rollback the current to meet the power limit.

Page 12: Software Interface
The MX-50 contains a speaker and an LED, both of which indicate that the X-ray tube is turned on. The LED is visible on the back side of the MX-50 package, but in some applications the Mini-X-OEM and MX-50 is inside an enclosure. Pins 3 and 4 can be used to drive an external indicator, such as the LED sketched above. - Page 13 If your computer is not on the Internet or your Firewall or Administrative settings prevent automatic installation, then you will need to install the drivers manually. The drivers are on the installation CD and can be downloaded from Amptek’s website. Go to the "Mini-X Drivers" directory and run the appropriate "dpinst" file for your OS.

When the brass safety plug is installed in the cover (figure 16, middle) and screwed onto the Mini-X- OEM it meets the radiation safety requirements of Section 1.2. For personal protection always install the safety plug into the cover and attach to the Mini-X-OEM when not in use. The Mini-X-OEM ships from the factory in this configuration. -
Page 18: Radiation Levels And Example Shielding
XRF from the shielding material. CAUTION: The Mini-X-OEM is only one component of an X-ray instrument. It is the responsibility of the user, the OEM customer, or experimenter to provide a fail-safe metal enclosure to prevent escaping radiation while using this product. The final product (turn-key system) must comply with local government regulations to protect personnel from exposure to radiation. - Page 19 Note also that these pins can provide the power to the HVPS and to the monitor/control circuits. For customers who do not want to use the AC/DC supply provided by Amptek, these pins on J3 may be used as an alternate power supply connection. Note that the input power is 12 VDC and must go to both pins 1 and 2 (pin 2 supplies the HVPS while pin 1 supplies the control circuits).
