摘要：

An edge database is presented for divertor discharges in JET with various configurations: single null upper/lower (SNU/SNL), double null (DN), delB drift towards or away from the target and various divertor target materials (Be and C). We present the scaling of the scrape-off layer (SOL) parameters (i.e. density, temperature and their radial profiles) with main plasma parameters for divertor discharges with: I(p) = 3.2 MA, [n(e)BAR] = 1-7 X 10(19) m-3 and B(t) = 2.2-3.4 T. Results are presented for ohmic, L-Mode and H-mode discharges with additional heating (NBI and ICRH) up to 10 MW. The parameters were measured in the main SOL and at the divertor plates. A comparison is made for discharges when gas puffing was used either at the midplane OT at the X-point. The results are compared with similar scalings obtained in limiter plasmas and with the predictions by simple SOL models.
