Film and journal article on ACHIP, the particle accelerator on a chip program
A nice article on ACHIP has been published in the DESY research magazine. Issue 1/2019 is dedicated to the plasma acceleration of charged particles. Since the dielectric laser acceleration is related, our scientific progress towards a particle accelerator on a chip is also shown there, see p. 29 here (pdf, 4.4 MB).
A film about ACHIP that the American Physical Society (APS) had shot about ACHIP is similarly well done. The locations were the laboratories of the two ACHIP speakers, Professor Byer and Professor Hommelhoff, Stanford and Erlangen. Here you can find the 6-minute film on Youtube.
