A linear rise approximation (LRA)arrival timing method provides restricted timing resolution forpulses with nonlinear rise. It reaches 1/20th of the samplingperiod, if the relation between signal shaping and sampling rate isoptimized. We introduce a nonlinear rise approximation (nLRA),which reduces the sampling phase error (SPE) down to lessthan 1/100th of the sampling period. The proposed timingalgorithm uses a single free parameter that can easily be adjustedfor various radiation detectors. The technique permits using arather slow pulse shaping and low sampling rates, thus stronglyreducing power consumption and the costs of the system. A high-density DAQ system integrating over 2000 channels inside anOpenVPX crate is presented. A prototype has been tested in theproton beam at cooler synchrotron (COSY) at Jülich ResearchCenter (Germany).}, cin = {ZEA-2 / IKP-1}, ddc = {620}, cid = {I:(DE-Juel1)ZEA-2-20090406 / I:(DE-Juel1)IKP-1-20111104}, pnm = {631 - Accelerator R $\&$ D (POF3-631)}, pid = {G:(DE-HGF)POF3-631}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000481936800004}, doi = {10.1109/TNS.2019.2923382}, url = {https://juser.fz-juelich.de/record/868234}, }
