# DIALS core meeting 2022-10-13

## Previous Actions

- [ ] ND to review: TOFBeam - A time-of-flight beam in dxtbx [`cctbx/dxtbx#492`](https://github.com/cctbx/dxtbx/pull/492) ([prev](https://dials.github.io/kb/core/2022-03-03#proposal-for-a-time-of-flight-beam-in-dxtbx))
    - David McD going to revisit this and push for PR merges in context, ignore for now but will be coming up very soon - there are people with a great need for this!
