System

The ALDAS program is designed to read data quickly from silicon strip detectors. ALDAS also features support for the new trigger control card (TCC).

Features

This version of the program has five main functions.

Threshold scan. When you click this button, you are asked for the min and max thresholds, and the calibration voltage.

The program then collects the data from the detector. After all the data has been collected the program displays a window showing the results of fitting the data to an error function.

[Threshold Scan View]

Clicking on a channel in this view shows you the raw data and the fitted curve.

The other three major functions are as follows:

Strobe delay scan
Noise scan
Collecting raw data with either internal triggers or using an external trigger source.

Explanations of these scans can be found in the help manual for the program.

New Features in Version 1.1

Now ALDAS allows you to select inverted hit polarity for each module attached to the system.

There is a new document, which allows you to take data from an external trigger source.

More information can be found in the help files.

Requirements

To use this program, you must have a Win95/NT machine, and the MXI-2 interface card. Also helpful are the DSP card, SLL card, and a silicon module. You may also use the TCC card if one is available. The program automatically checks for the TCC card and uses it if it is installed.

Downloading the program

After you have downloaded the ZIP file, extract the files into the ALDAS directory. If you use WinZip, it should extract the files into the ALDAS subdirectory automatically. For information on using ALDAS read the help file.
