Abstract

Purpose

Hundreds of digital beam position monitor processors (DBPM) are required to be produced during the construction of projects such as High Energy Photon Source (HEPS) and the upgrade project of the Beijing Electron Positron Collider (BEPCII), which brings great challenges to the test work. In order to achieve accurate, fast, and complete mass production tests of DBPMs, an automatic test system (ATS) has been developed in this article.

Methods

According to the test items of DBPM, the standardized testing software flow is designed based on virtual instrument program control technology and experimental physics and industrial control system (EPICS), which realize automatic adjustment of test parameters and automatic acquisition of test result data.

Results and conclusions

The ATS can realize one-button testing of channel coefficients, channel linearity, attenuator linearity, beam current dependence (BCD) and sampling signal-to-noise ratio (SNR), and generate test reports. The total test time is less than 3 minutes, which is significantly more efficient compared to manual testing. More than 90 BEPCII DBPMs has been tested by this ATS in the lab. The test results proved that such a system could automatically recognize defective products and satisfy the requirements of mass testing.
