BITS Starter

APS 16BM B & D operations using Bluesky, with BITS structure

One-time Setup

Installing your own BITS instrument

conda create -y -n 16bm-bits-b python=3.11 pyepics
conda activate 16bm-bits-b
pip install apsbits

16BM-D uses environment 16bm-bits-d.

Creating a New Instrument

For each new instrument to be added, create initial configuration. (Modify the YOUR_INSTRUMENT_NAME below used for 16BM-B. Python packages must now start with a number, that's why bm comes first.)

export YOUR_INSTRUMENT_NAME=bm16_b
create-bits $YOUR_INSTRUMENT_NAME

Install all under src/ into the conda environment:

pip install -e .[all]

IPython console Start

Activate the conda environment:

conda activate 16bm-bits-b

To start the bluesky instrument session in a ipython execute the next command in a terminal:

ipython

Jupyter Notebook Start

Start JupyterLab, a Jupyter notebook server, or a notebook, VSCode.

Starting the BITS Package

Either bm16_b or bm16_d:

from bm16_b.startup import *

Run Sim Plan Demo

To run some simulated plans that ensure the installation worked as expected please run the next commands inside an ipython session or a jupyter notebook after starting the data acquisition:

from bm16_b.plans.sim_plans import *
RE(sim_print_plan())
RE(sim_count_plan())
RE(sim_rel_scan_plan())

Configuration files

The files that can be configured to adhere to your preferences are:

• configs/iconfig.yml - configuration for data collection
• configs/logging.yml - configuration for session logging to console and/or files
• qserver/qs-config.yml - contains all configuration of the QS host process. See the documentation for more details of the configuration.

queueserver

The queueserver has a host process that manages a RunEngine. Client sessions will interact with that host process.

Run a queueserver host process

Install screen

sudo apt install screen

Use the queueserver host management script to start the QS host process. The restart option stops the server (if it is running) and then starts it. This is the usual way to (re)start the QS host process. Using restart, the process runs in the background.

./src/YOUR_INSTRUMENT_NAME_qserver/qs_host.sh restart

Run a queueserver client GUI

To run the gui client for the queueserver you can use the next command inside the terminal:

queue-monitor &

Shell script explained

A shell script (./src/YOUR_INSTRUMENT_NAME_qserver/qs_host.sh) starts the QS host process. Below are all the command options, and what they do.

(BITS_env) $ ./src/YOUR_INSTRUMENT_NAME_qserver/qs_host.sh help
Usage: qs_host.sh {start|stop|restart|status|checkup|console|run} [NAME]

    COMMANDS
        console   attach to process console if process is running in screen
        checkup   check that process is running, restart if not
        restart   restart process
        run       run process in console (not screen)
        start     start process
        status    report if process is running
        stop      stop process

    OPTIONAL TERMS
        NAME      name of process (default: bluesky_queueserver-)

Alternatively, run the QS host's startup command directly within the ./qserver/ subdirectory.

cd ./qserver
start-re-manager --config=./qs-config.yml
