Coarsely segmented (pitch > 1 mm) zigzag-shaped anode strip arrays have been shown to have considerable advantages over similarly pitched straight strip arrays for standard planar MPGDs, including GEM, Micromegas, and micro-RWELL detectors. Once the geometric parameters of the zigzag are precisely tuned for a specific detector application, the spatial resolution remains high and approximately...

Additive manufacturing is a popular technique currently providing new opportunities in several domains. In this proposed work, we applied the above-mentioned technology to detector construction. We had hypothesized that a fully automated 3D printing of a detector would be ideal to drastically reduce: 1) detector construction cost and assembly time 2) the probability of mistakes during...

The search for weakly interacting, light particles that couple to photons received significant attention in recent years. When those particles are produced at high energies, they may decay in two collinear photons that can be detected by an electromagnetic calorimeter system. The typical dominant background in searches for those high energetic weakly particles are single, high energetic...

Simulation of High Energy Physics experiments is inevitable for both detector and physics studies. Detailed Monte-Carlo simulation algorithms are often limited in the number of samples that can be produced due to the computational complexity of such methods, and therefore faster approaches are desired. Generative Adversarial Networks (GANs) is a deep learning framework that is well suited for...

Theoretical prediction for the distribution of the angle between electrons and positrons originating in internal pair creations is a monotonic featureless decrease with the opening angle. Recent studies on excited states of 8Be and 4He nuclei, made in ATOMKI, Hungary, however, revealed deviations from this expectation. If true, such a result may have a fundamental...

A muon collider has a great potential for high energy physics. It combines the high precision of electron-positron machines, with a low level of beamstrahlung and synchrotron radiation, and the high centre-of-mass energy and luminosity of hadron colliders.
