Wires (wire segments) in WCT are described by their physical endpoints and their logical locations in terms of various numbers and indices. A "WCT wire file" provides an exhaustive list of this info for each wire. Note, WCT can generate wire files in a parameterized way given basic information about an anode plane. See

$ wirecell-util make-wires --help

However, some wires are taken from other programs and then converted to WCT wire files. See

$ wirecell-util convert-oneside-wires --help

• ChannelWireGeometry_v2.txt a dump of MB wires from larsoft in so called "celltree wire format"
• ./microboone-celltree-wires-v2.json.bz2 the conversion of the above
• ./microboone-celltree-wires-v2.1.json.bz2 the conversion of the above, fixing wire index in plane

See this plot for graphical representation of these wires. (Note, a transform may be applied to their locations in WCT, so don't take the positions shown here as gospel.)

• WireGeometry_dune35t_v5_tpc1.txt "celltree wire format" for DUNE 35t prototype
• ./dune35t-tpc1-celltree-wires-v5.json.bz2 WCT wire file from above
• ./pdsp-wires.json.bz2 protoDUNE single-phase wires for one APA, generated by make-wires

The field responses are generally calculated by Garfield (so called "truth responses" may be from some other source). The data produced by Garfield are in the form of a family of files named by their impact position and plane letter. Each file spans that impact position relative to many wires. To process this data into "WCT field response files" see:

$ wirecell-sigproc convert-garfield --help

The required "origin" and "speed" are not recorded in the files directly and must be provided on the command line of this converter. Note the converter takes as input a .tar.gz of the Garfield directory of <impact>_<letter>.dat files (and no other files).

• dune_4.71.tar.gz DUNE APA Garfield data
• ./garfield-1d-3planes-21wires-6impacts-dune-v1.json.bz2 WCT field response file from above.

MB has many sets of field response files. The nominal set is called ub_10 (uboone wire model with fields starting at 10cm from the wires).

• ub_10.tar.gz nominal MB Garfield data
• ./ub-10.json.bz2 WCT field response conversion

Alternatives in two dimensions have been created in order to understand the MB shorted wires and a Garfield normalization issue. The shorted wire alternatives have labels

uv-ground

the U and V wires are shorted

vy-ground

the V and Y wires are shorted

The normalization issue is that early Garfield runs seem to produce collection responses which when integrated gives a total charge of about 2.04 electrons instead of the expected 1.0. Initially the responses were normalized such that the average collection wire integral was 1.0. This technique utterly fails for shorted wires where "collection" becomes ill defined. The variants are labeled as:

wnormed

normalize by the average collection (W wire) integral method

absolute

take Garfield normalization as-is

half

simply scale by 0.5

These are the files:

• ./ub-10-absolute.json.bz2
• ./ub-10-half.json.bz2
• ./ub-10-wnormed.json.bz2
• ./ub-10-uv-ground-absolute.json.bz2
• ./ub-10-uv-ground-half.json.bz2
• ./ub-10-uv-ground-wnormed.json.bz2
• ./ub-10-vy-ground-absolute.json.bz2
• ./ub-10-vy-ground-half.json.bz2
• ./ub-10-vy-ground-wnormed.json.bz2

The WCT simulation can produce proper intrinsic noise waveforms based on a measured noise amplitude distribution expressed in frequency domain. These are provided as simple text files which are then converted to "WCT noise files". For info on this conversion see

$ wirecell-sigproc convert-noise-spectra --help

As the procedures are improved the vN version label is increased.

• ./microboone-noise-spectra-v1.json.bz2
• ./microboone-noise-spectra-v2.json.bz2

Note, strictly, these types of files should not be included here and may be removed in the future. The current WCT drift and detector response simulation relies on an external interaction/tracking simulation (ie, Geant4 based) to provide initial distribution of energy depositions or of ionization electrons. A couple samples of these are provided.
