X-point radiator and power exhaust control in configurations with multiple X-points in TCV

The purpose of this data repository is to provide supplementary material to the article entitled "X-point radiator and power exhaust control in configurations with multiple X-points in TCV" [Gorno et al., submitted to PoP, 2024]. The divertor imaging data is included in .avi format for the experiments in TCV presented in this article, as well as an experiment presented in [Gorno et al., PPCF, 2023] (https://doi.org/10.1088/1361-6587/acad26).  See below for details on each of the divertor imaging diagnostics included here.

77021_JF_MANTIS.avi : Imaging data from the MANTIS diagnostic in the Jellyfish (JF) configuration (#77021). A snapshot of this video at t=1.125s is presented in Fig. 16 in [Gorno et al., submitted to PoP, 2024]. This corresponds to the data used in the estimation of electron temperature distribution presented in Fig. 17 (a) in [Gorno et al., submitted to PoP, 2024].

77067_SN_MANTIS.avi : Imaging data from the MANTIS diagnostic in the Single Null (SN) configuration (#77067). This corresponds to the data used in the estimation of electron temperature distribution presented in Fig. 17 (b) in [Gorno et al., submitted to PoP, 2024].

70424_SF-_MANTIS.avi : Imaging data from the MANTIS diagnostic in the Snowflake Minus (SF-) configuration (#70424). This is a similar experimental configuration as the SF- (#70321, #70497) discharges presented in [Gorno et al., PPCF, 2023].

70424_SF-_Fastcam.avi : Raw imaging data from the fast imaging camera in the Snowflake Minus (SF-) configuration (#70424). 

Notes regarding each diagnostic:

MANTIS [Perek et al., RSI, 2019] : Multi-spectral imaging diagnostic measuring 9 spectral lines with an integration time of 4.9 ms, from top left to bottom right: HeI 729 nm, D 7->2, HeI (706 nm), Fulcher, HeI (667 nm), D 5->2, D 4->2, CIII, D 3->2. The data in these videos has been compressed and scaled. Note that the poloidal field of view is mirrored horizontally about the central column with respect to the standard TCV cross-section, with the machine LFS on the left of the image. 

Fast imaging camera [N. Offeddu & C. Wüthrich, RSI, 2022] : Imaging diagnostic measuring the HeI line (587.5 nm). With an exposure time of ~0.01 ms, this system is capable of imaging the plasma on a turbulent time-scale. The data in this video has been scaled and is not absolutely calibrated. Note that, unlike the MANTIS data, the images have been mirrored horizontally about the central column.

MANTIS and the fast imaging camera both have the same field of view. They image the divertor, part of the central column, and the lower part of the confined region, see Fig. 1(d) in [Gorno et al., submitted to PoP, 2024].
