[en] To perform nuclear astrophysics (NA) experiments in laboratory, a high current ion-beam is required due to its low fusion or capture cross-section. Now high current beam will generate a huge amount of heat inside the target. Such high temperature can cause melting of target. So a cooling arrangement is required to perform such high current experiment without melting issues. Now heat generated inside a thin target (much less than projectile range) is much less compared to thick targets (greater than projectile range). And for that reason melting is not such a big issue for thin targets
