Event built LArPix-v2 cosmics data collected on Monday, July
20th, 2020 at LBNL in a LArTPC with 10cm max drift length has
been uploaded to this space.

Also uploaded is an example script to parse the hdf5 files.
To run: python3 -i example-parsing.py [path to hdf5 file(s)]

The v1rev2 3x3 chip pixel tile served as the anode plane.

Each chip had 49 active channels routed out to pixel pads in
a 7x7 pixel grid. The following channels were not routed out
to pixel pads and left floating:
6, 7, 8, 9, 22, 23, 24, 25, 38, 39, 40, 54, 55, 56, 57

The following chip IDs had metal shielding cans affixed to the
chip package:
1-1-12
1-1-13
1-1-14
1-1-23

The nominal pixel pad area fill factor is 3.55mm. Two chips
(1-1-24 and 1-1-34) had a larger pixel pad area fill factor
of 4mm.

Visualization of this data can be performed with larpix-geometry:

A yaml file which encodes chip id and channel to x and y position
mapping can be generated with layout-2.2.1.py
