From 53525d4e213c4ff9e81a2d43ce4d895132810fd9 Mon Sep 17 00:00:00 2001 From: Gabor Galgoczi Date: Tue, 24 Mar 2026 16:33:46 +0000 Subject: [PATCH 01/39] feat: add GPU wavelength shifting (WLS) physics Implement end-to-end GPU-side wavelength shifting: GDML property extraction -> ICDF texture -> GPU competing absorption + re-emission. WLS absorption competes with bulk absorption and Rayleigh scattering in propagate_to_boundary. RNG consumption is conditional on WLS presence to preserve sequence alignment for non-WLS geometries. New files: U4WLS.h, qwls.h, QWls.hh, QWls.cc, test geometry/config. Modified: sproplist (SPARE11->WLSABSLENGTH), sstandard, snam, sstate, qsim (propagate_to_boundary), QSim, QU, U4Tree, CMakeLists. Tested: 990/1000 photons shifted 350nm->487nm, energy conservation and isotropy validated via GPUPhotonSourceMinimal. --- config/wls_test.json | 30 +++++ qudarap/CMakeLists.txt | 5 + qudarap/QSim.cc | 25 +++++ qudarap/QSim.hh | 2 + qudarap/QU.cc | 2 + qudarap/QWls.cc | 147 +++++++++++++++++++++++++ qudarap/QWls.hh | 46 ++++++++ qudarap/qsim.h | 73 ++++++++++++- qudarap/qwls.h | 153 ++++++++++++++++++++++++++ sysrap/snam.h | 4 + sysrap/sproplist.h | 2 +- sysrap/sstandard.h | 17 ++- sysrap/sstate.h | 4 +- tests/geom/wls_test.gdml | 144 ++++++++++++++++++++++++ u4/CMakeLists.txt | 1 + u4/U4Tree.h | 29 +++++ u4/U4WLS.h | 230 +++++++++++++++++++++++++++++++++++++++ 17 files changed, 909 insertions(+), 5 deletions(-) create mode 100644 config/wls_test.json create mode 100644 qudarap/QWls.cc create mode 100644 qudarap/QWls.hh create mode 100644 qudarap/qwls.h create mode 100644 tests/geom/wls_test.gdml create mode 100644 u4/U4WLS.h diff --git a/config/wls_test.json b/config/wls_test.json new file mode 100644 index 000000000..b8572b5b9 --- /dev/null +++ b/config/wls_test.json @@ -0,0 +1,30 @@ +{ + "torch": { + "gentype": "TORCH", + "trackid": 0, + "matline": 0, + "numphoton": 1000, + + "pos": [0.0, 0.0, 0.0], + "time": 0.0, + + "mom": [0.0, 0.0, 1.0], + "weight": 0.0, + + "pol": [1.0, 0.0, 0.0], + "wavelength": 350.0, + + "zenith": [0.0, 1.0], + "azimuth": [0.0, 1.0], + + "radius": 0.0, + "distance": 0.0, + "mode": 255, + "type": "disc" + }, + + "event": { + "mode": "DebugLite", + "maxslot": 1000000 + } +} diff --git a/qudarap/CMakeLists.txt b/qudarap/CMakeLists.txt index 0f2503a69..9c4ac1d0e 100644 --- a/qudarap/CMakeLists.txt +++ b/qudarap/CMakeLists.txt @@ -51,6 +51,8 @@ set(SOURCES QScint.cc QScint.cu + QWls.cc + QCerenkovIntegral.cc QCerenkov.cc QCerenkov.cu @@ -120,6 +122,9 @@ SET(HEADERS QScint.hh qscint.h + QWls.hh + qwls.h + QCerenkovIntegral.hh QCerenkov.hh qcerenkov.h diff --git a/qudarap/QSim.cc b/qudarap/QSim.cc index aa8130a24..b7c59c27f 100644 --- a/qudarap/QSim.cc +++ b/qudarap/QSim.cc @@ -36,6 +36,7 @@ #include "QRng.hh" #include "QTex.hh" #include "QScint.hh" +#include "QWls.hh" #include "QCerenkov.hh" #include "QBnd.hh" #include "QProp.hh" @@ -181,6 +182,28 @@ void QSim::UploadComponents( const SSim* ssim ) } + const NP* wls_icdf = ssim->get(snam::WLS_ICDF); + const NP* wls_mat_map = ssim->get(snam::WLS_MAT_MAP); + if( wls_icdf == nullptr || wls_mat_map == nullptr ) + { + LOG(LEVEL) << " wls_icdf or wls_mat_map null — no WLS materials in geometry " ; + } + else + { + const NP* wls_tc = ssim->get(snam::WLS_TIME_CONSTANTS); + if( wls_tc ) + { + unsigned hd_factor = 20u ; + QWls* qwls_ = new QWls( wls_icdf, wls_mat_map, wls_tc, hd_factor ); + LOG(LEVEL) << qwls_->desc(); + } + else + { + LOG(error) << " wls_icdf and wls_mat_map present but wls_time_constants missing " ; + } + } + + // TODO: make this more like the others : acting on the available inputs rather than the mode bool is_simtrace = SEventConfig::IsRGModeSimtrace() ; if(is_simtrace == false ) @@ -267,6 +290,7 @@ QSim::QSim() sev(qev->sev), rng(QRng::Get()), scint(QScint::Get()), + qwls(QWls::Get()), cerenkov(QCerenkov::Get()), bnd(QBnd::Get()), debug_(QDebug::Get()), @@ -316,6 +340,7 @@ void QSim::init() sim->multifilm = multifilm ?

This caused GPU to produce zero hits with arrival time >100ns while G4 consistently showed 20% of hits in the 100-11000ns range. Now reads up to 3 scintillation components from the material properties (SCINTILLATIONTIMECONSTANT1/2/3, SCINTILLATIONYIELD1/2/3), splits the photon count proportionally, and creates separate gensteps for each component with its own time constant.
