Abstract or Summary
  • This project implements the control of an AUTOMATIC GAMMA WELL counting system with an AIM-65 microcomputer. All states and control signals to and from the AIM-65 are obtained via three VIAs (Versatile Interface Adaptors). Motor controls were implemented using triacs, operational amplifiers and TTL logic devices while the RTC (Real Time Clock) utilizes a 32.768 kHz quartz precision crystal and battery backup. The radiation detection system can handle solid or liquid phase gamma ray emitting samples. Samples may be prepared in 15mm X 110mm bottles or in 15mm X 125mm test tubes and placed in receptacles on the conveyor belt of the sample changer. Under software control, selected samples can be lowered into the well of the detector and counted. A hardcopy of the parameters used in setting up the experiment as well as the results may be obtained on a teletype.
