Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|

I delete the field within my DetectorConstructor destructor. Matter may come from that, right?

I've checked and particles are e-. But I've also see more clearly each step of the e-, what I haven't done before ... just drawn histograms of z-depth
Here is a piece of my output in attached file. I've indicated the coordinates columns, the prestep kinetic energy and poststep kinetic energy and type of interaction experiences by the e-.
What we can see is that at the beginning of the track the e- goes towards z < 0 axis and gain energy. It interacts in the Plaque (the detector is like a plane ionisation chamber with 2 planned electrodes calles Plaque and Signal, and gas between called Sensitive) and then goes towards the opposite electrodes.
I wonder whether this behaviour is physically correct or not, according to e- energy
