Yes good question, currently it can't perform that download.
If I can map each s(a,b) thermal cross section to a particular element or elements then I can add a flag to include them or not.
Currently these are processed but not included in the database of available cross sections.
I shall look into it.

Ok i think I have a method for the command line tool
I can add a flag for -sab and accept a list of stings. Each entry must be in this list of acceptable names.
The input strings can be checked against acceptable names define here https://github.com/openmc-dev/openmc/blob/efcc0c158edcc3e389eb20a5c5ffc4e0a65ef554/openmc/data/thermal.py#L30-L77
Then the unique sab names can be match to the urls in the endf list of h5 files containing thermal cross sections (botton of this page
For the api usage I notice the openmc.material.add_s_alpha_beta
sets a ._sab
attribute so that can be used to check if there are sab requirments in the material object
Sorry this is taking me a little while as I have a few projects to close out at the moment
from openmc_data_downloader.
@AI-Pranto I have had a go at adding this feature in the latest PR merge #16 there are a few examples on the readme.
The pip install on PyPi has also been updated to v0.3.0 https://pypi.org/project/openmc-data-downloader/#history
I am keen to improve it if you have any suggestions

Sorry for the late response here.
LGTM, Thanks @shimwell!
Just one last request here, Currently we have neutrons and Tsl data only at a single temperature 294
. Can we include neutrons data at 250 K
, 293.6 K
, 600 K
, 900 K
, 1200 K
, and 2500 K
? We can update our current ENDF-B-VII.1-NNDC data storage by downloading pre-processed data from openmc-data Is it ok with you?
@shimwell Did you face data storage limit in github?
from openmc_data_downloader.
Yep there is a storage limit per repo so I guess that each temperature could be a separate repo to avoid that.
The repos on this organisation currently make use of these scripts to download data and process it into h5 data.
They are all templates a single repository with library specific modifications
So I would need another base repository to template that would take a different approach
The new template would download from https://openmc.org/official-data-libraries/ extract and self commit to the repo using a GitHub action
This might take a little while to sort out and then extend to do different temperatures but it is certainly now on the todo list, thanks for the suggestion
from openmc_data_downloader.
Thanks, @shimwell :)
