Particle accelerators have become indispensable tools in fundamental charged-particle and beam-physics research, medical diagnostics and therapy, security screening, and many other applications. A small number of large, GeV-scale machines, often call...
The commercially available compact electron linear accelerator (LINAC) products used for high-energy imaging of dense and/or thick objects offer accelerated electron beams in an energy range from 1 MeV to 10 MeV with focal spot sizes generally from 1...
This work presents a covariance-aware extension of the hybrid nonlinear-kicker (NLK) injection framework. While previous baseline studies established centroid action reduction and hardware-aware NLK placement for idealized beams, the present study ad...
Ultrasonic Lamb waves are promising for the nondestructive evaluation of silicon wafers; however, their dispersive, multimode, and orientation-dependent propagation complicates multidirectional measurements in anisotropic media. This study presents a...
A remote automation controller NA64-DTC was developed, constructed, and integrated for the so-called “DESY Table” motorized platform, widely used in CERN East-Area and North-Area experimental installations. The device interfaces with the...
Optical fibre beam loss monitors (oBLMs) are in use at several accelerator facilities worldwide as an online, low-cost, and reliable beam loss monitoring solution. They measure beam loss locations through time-of-flight analysis of Cherenkov radiatio...
Electro-optical bunch arrival time measurement is a method to monitor the timing of bunches in predominantly linear electron accelerators to below femtosecond precision. Despite the method being well established, a stable and fully available measurem...
Space gravitational wave detection missions demand ultra-stable calibration of inertial sensor capacitive sensing. Conventional dynamic methods suffer from mechanical vibration noise and bias separation difficulties, while large-displacement operatio...
The bias-dependent capacitance of varactors can introduce harmonic distortion into the circuits where they are utilized. A gate capacitance model valid through inversion–depletion has been presented for GaN HEMT varactors in the drive for their...
The development of FLASH particle therapy, especially proton therapy, characterized by ultra-high dose rates (>40 Gy/s), presents significant challenges for dosimetry and beam monitoring. For example, ionization chambers (ICs) exhibit charge recom...
In proton beam therapy, ideally, beam monitoring should be non-invasive to provide online real-time feedback, such that the total dose delivered to the patient is not significantly affected. The invasiveness of the Supersonic Gas-Curtain-Based Ioniza...
Nonlinear kickers (NLKs) enable off-axis injection in ultralow-emittance storage rings by providing a strong kick to the injected beam while remaining nearly transparent to the stored beam. In hybrid schemes, a conventional four-kicker bump defines t...
