4 stepper motors – already delivered
Test with L-Card controller and Delphi prog. – passed
Mechanical production – in progress
USB L-CARD - controller

9. Articles preparation
In preparation - ”Development of data acquisition and diagnostic system for PANDA pellet target”, Journal: “Instruments and Experimental Techniques” (Scopus) end of 2018 or 2019 year.

10. Transfer of the first prototype from FZJ to ITEP
Truck with the first prototype of the Pellet target arrived ITEP on 28 May.

11. Transfer of the first prototype from FZJ to ITEP
The transfer was succeeded on 28 May 2018
With the parts from the first prototype the configuration of the second prototype will be completed
Preparation of the draft of the TDR
Writing of the draft of the Pellet target TDR is going on.
The prototype is not completed. Some tests for TDR can not be performed. Waiting for transfer from FZJ.
R&D studies are not finished. Some results are still absent.
