Rik Gran's public WALTA page

This will grow to be my personal collection of useful information about WALTA and the Quarknet DAQ card. Some of this information will be mirrored elsewhere eventually.

Data summary

Go to summary.html to see a quick quasi-weekly update of data and coincidences.

Also see runsummaries to check your data. I have copied a summary of the most recent files you have uploaded. (New, as of October 2004, we really are, but they are not immediate or automatic. This will happen at least as often as the coincidence analysis.)

Results from the 2004 workshop muon decoherance experment at muondecoherance.html and air shower coincidences at airshowercoincidence.html

Presentations

You can view one of my presentations. This directory contains pdf, ppt, and sxi versions of the same talk.

Analysis

A random collection of analysis of the Quarknet DAQ card, our rooftop muon telescope setup, our rooftop air shower setup, and the minime air shower array. This is all in a single PDF for convenience, but it will be broken into its separate components as different pieces are completed.

Some information about recent data sets taken at UW. This document will eventually be split and put into different manuals and documentation, but for now it is all together.

Oh, and it is not complete, either in style or content, but this first draft is readable. And it contains important information that has not been propagated to the correct users manuals.

Software

LabVIEW DAQ

You probably want to use our LabVIEW GUI interface to run your card. It is available at http://d0.phys.washington.edu/~burnett/walta/qnet_daq.

Prototype of data file checks for school data: summary.html

Linux DAQ

Get this as part of the Analysis code below. Look for qnetdaq.

Analysis code

We might want to share data between WALTA, CROP, CHICOS, or other cosmic ray experiments with excellent time resolution. Here is a proposed event data format which might allow us to easily write code to look for coincidences or other patterns. eventformat.txt

A better collection of C++ analysis code that I have used to explore our data. Updated January 2005 with some bugfixes and useful examples. This tar.gz file contains some simple skeletons that do useful stuff like print human-readable or spreadsheet-readable output to the screen and also extract some summary information from the file. Please send me a note if you use these things, or else I will continue to update stuff only for my own amusement.

See waltasource.tar.gz

The easiest one is a utility to convert the DAQ strings into events in a format suitable for a spreadsheet. Right now this is an old version, you probably want to use the updated version in the file above. daq2txt
These tools may be obsoleted by other software tools that we develop.

Data

I have posted some one-site data at http://neutrino.phys.washington.edu/~gran/waltadata for a sample of what the DAQ card produces.

What is there now is basically from Midnight October 6th to 5pm October 8th. I can post more.
