In recent years, the most powerful supercomputers have already reached megawatt power consumption levels, an important issue that challenges sustainability and shows impossibility of maintaining this trend. To date, prevalent approach to super-computing is dominated by CPUs GPUs. Given their fixed architectures with generic instruction sets, they been favored lots tools mature workflows which led mass adoption further growth. However, reconfigurable hardware such as FPGAs has repeatedly...
The production of vector mesons in deep inelastic scattering is an interesting yet scarsely explored channel to study the transverse spin structure nucleon and related phenomena. COMPASS collaboration has performed first measurement Collins Sivers asymmetries for inclusively produced $\rho^0$ mesons. analysis based on data set collected $2010$ using a $160\,\,\rm{GeV}/c$ $\mu^+$ beam impinging transversely polarized $\rm{NH}_3$ target. $\rho^{0}$ are selected from oppositely charged hadron...

Data logging and complex algorithm implementations acting on multichannel systems with independent devices require the use of time synchronization. In case Gas Electron Multipliers (GEM) Thick-GEM (THGEM) detectors, biasing potential can be generated at detector level via DC to converters operating floating voltage. this case, high voltage isolation buffers may used allow communication between different channels. However, their add non-negligible delays in transmission channel, complicating...
