Menu bar

File

---

Open frame…

Opens a dialog that allows to open previously recorded frame files using a *.dsc file

Save data…

Opens a dialog that allows to save current frame in various file formats
Relevant file formats: .txt, .clog, .png, .tif, .tiff

Load factory config

Looks into (Pixet_folder)\factory\ and searches for MiniPIX-{chip_ID}.xml and configures the device by it.

View

---

Mirror Image

Toggle option, allows to display the detector window mirrored along Y axis

Rotate image

alows to rotate displayed data in detector window by 90°, 180° or 270° clockwise

Show grid

Toggle option, allows to display an overlay in detector window showing the pixel grid

Ensure aspect ratio

toggle option, keeps aspect ratio constant when resizing the Pixet window

Settings

Change password for Pixet Pro

internal development option

Scripting

---

(Menu Scripting, or click on the icon with two papers at the toolbar.)

Python scripting opens Python scripting plugin, that enables to controll the device using Python	Python plugin (Pixet Pro below it - Basic has fewer icons)
template_script.py runs an example script. If unaltered, performs 3x 1s acquisition and saves the frames into Pixet parent directory as .png files

Image properties

---

allows to set min and max values for view of the current measurement

Measurement

---

Mode	Imaging - measures number of hits in each pixel during selected time period Tracking - measures energy of hits in each pixel during selected time period
Frames	set how many frames will be measured
Exposure [s]	set the exposure duration of each frame
Sum	if checked, sums all measured frames in the detector window
Play	starts the measurement. Automatically repeats when finished
Image	takes a single image with selected exposure time

Image Info

---

[X,Y]	gives X,Y coordinates of selected pixel or pixel under the mouse pointer
Count	gives number of hits in selected pixel or pixel under the mouse pointer
Min	min number of hits in image or selected area
Max	max number of hits in image or selected area
Pixel count	number of hit pixels in image or selected area
Total	total number of hits in image or selected area
Mean	mean number of hits in image or selected area

Histogram

---

(only if imaging mode is selected)

Spectra

---

(only if tracking mode is selected) Energy [keV]

Size [pix]

Timeline

Status bar

Messages	shows system messages. Broom icon = clear log. Toggle option to automatically open when new message
T	duration of current experiment
A	current/total no. of measurements. Does not work when repeating or when taking single images
Measurement progress bar	Shows progress of current measurement. Does not work when repeating or when taking single images

Getting started with the PIXet Basic

Quick intro to using the Pixet Basic program. For the Experiments cookbook, see: EDU Kit experiments cookbook

Collecting Data

1. Connect the MiniPIX EDU camera, wait for 10 seconds and launch the software Pixet Basic.
2. The settings supposed to be modified while performing the experiments. See right image: The two arrows show the only place to modify the settings.
3. The collected visual data will be displayed on the black screen and the additional data (counts, histograms, etc.) is displayed in the two sections- Image Info and Spectra. See right image: The data of the experiment will be displayed in the two sections
4. The image info shows energy in the “Info” tab and counts of individual particles in the “Tracks” tab.
5. The spectra section shows the energy, size, and time of individual particles in respective tabs. Note: To enlarge the spectra results, click on the rectangle at the top right corner of the spectra window.

Exporting Data

1. Select the energy graph in spectra and right-click on the histogram in the spectra section and click on Save to File.	Figure 4. The histogram of collected data is being exported as ASCII
2. Enter the file name and select ASCII Vertical in Save as type drop-down menu. Click on Save.	Figure 5. The type of file in the save window should be vertical to make sure that we get the whole histogram
3. Next open Excel. Click on Open > Browse and browse to the saved file. Select All Files from the drop-down menu next to the File name field, select the file and click open.	Figure 6. The Open window of excel showing the “vtxt” file
4. Select Delimited in the Text Import Wizard window and click on Finish.	Figure 7. Excel delimiting the data to sort it in different columns
5. The first two columns of sheet are the list of the energy of alpha particles, the next two columns are for electrons, the next two are muons and the last two are dots.
6. Now select the first two columns and click on the Insert menu. In the Charts section, click on the Scatter chart and select Scatter with Straight Lines to get the histogram.
