TEM Scripts Collection

A collection of Python scripts/apps/utilities designed for automating and enhancing workflows with Rigaku Synergy-ED instruments and JEOL TEMs. This repository contains various standalone utilities designed to simplify common tasks in electron microscopy.

Requirements

• Python 3.8 (higher not tested)
• comtypes (Windows only — communicates with the JEOL TEM3 COM server)
• Additional requirements per script (see individual .py files); global requirements.txt contains all packages

Note: PyJEM is no longer required. All scripts communicate directly with the JEOL COM interface via comtypes.

Installation

1. Clone this repository:

git clone https://github.com/danielnrainer/TEM-scripts.git
cd TEM-scripts

2. Install common dependencies:

pip install -r requirements.txt

Scripts

• beam_blank.py - Control beam blanking on JEOL microscopes via the JEOL TEM3 COM interface
• beam_blank_comtypes.py - Alternative beam blank controller using direct comtypes COM access (no PyJEM dependency)
• HT_ramping.py - High-tension ramping utility; ramps the accelerating voltage between setpoints at a controlled rate via the JEOL TEM3 COM interface
• stage_logger.py - Logging script (CLI only) for stage positions of JEOL TEMs and Synergy-ED diffractometers

Usage

Each script is standalone and can be run independently. Navigate to the script's directory and run it using Python:

python script_name.py
