Monitoring of Argon plasma in a coating manufacturing process by utilising IR imaging techniques Thermal Recordings (NPZ Files)
Description
This dataset contains the thermal imaging recordings made during the experiments investigating the effect of gas flow rate on the shape of the plasma. The index at the end of the file name denotes the order they were taken. The plasma tool head is positioned on the right of the image with the plasma and powder travelling from the right to the left of the image.
These files are the temperature exported at an emissivity of 0.74, the emissivity of the tool head. These are the corresponding files for the recordings in the collection Thermal Camera Recordings (CSQ Files).
File Format
The files are in NPZ format and can be loaded into Python using the np.load method. The array shape NxHxW where N is the number of frames, H is height and W is width.

Recording Notes
- sheffield_doe_flowrate_gasrate_0001: First run failed due to camera running out of battery
- sheffield_doe_flowrate_gasrate_0002: Good run
- sheffield_doe_flowrate_gasrate_0003: Starts with PULSE material flow rate rather than fixed
- sheffield_doe_flowrate_gasrate_0004: Powder level running low. May affect contrast and luminosity
- sheffield_doe_flowrate_gasrate_0005: Stopped early due to loss of power to recording PC
- sheffield_doe_flowrate_gasrate_0006: Ran out of gas
- sheffield_doe_flowrate_gasrate_0007: Redo of sheffield_doe_flowrate_gasrate_0006
- sheffield_doe_flowrate_gasrate_0008: Start of the recording had recording range set to 20 C - 120 C range and was corrected part way through.
