dc.description.abstract	We have measured the effect of 445 nm, high power diode laser, directed on the cathode of a SNICS ion source on the extracted beam currents of Cl-, Br- and I- ion beams. Beam current enhancement factors up to 9 were observed in Cs-depleted operation mode of the ion source. The photo-assisted enhancement is shown to scale with the laser power and depend strongly on the neutral Cs flux into the ion source. The effect of the laser diminishes with increasing Cs oven temperature. We present a qualitative model, supported by cathode current measurement, arguing that photoelectron emission and Cs coverage of the cathode surface could explain the observations.	en

Photo-assisted O− and Al− production with a cesium sputter ion source

Tarvainen, Olli; Kronholm, Risto; Laitinen, Mikko; Reponen, Mikael; Julin ,Jaakko; Toivanen, Ville; Napari, Mari; Marttinen, Miha; Kalvas, Taneli; Faircloth, Dan; Koivisto, Hannu; Sajavaara, Timo (American Institute of Physics, 2021)

It has been recently proposed that the production of negative ions with cesium sputter ion sources could be enhanced by laser-assisted resonant ion pair production. We have tested this hypothesis by measuring the effect ...
Experimental evidence on photo-assisted O− ion production from Al2O3 cathode in cesium sputter negative ion source

Tarvainen, O.; Kronholm, R.; Laitinen, M.; Reponen, M.; Julin, J.; Toivanen, V.; Napari, M.; Marttinen, M.; Faircloth, D.; Koivisto, H.; Sajavaara, T. (AIP Publishing, 2020)

The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could explain the higher-than-expected beam currents ...
Photo-enhanced O−, H− and Br− ion production in caesium sputter negative ion source : no evidence for resonant ion pair production

Hossain, Akbar; Tarvainen, Olli; Reponen, Mikael; Kronholm, Risto; Julin, Jaakko; Kalvas, Taneli; Toivanen, Ville; Kivekäs, Mikko; Laitinen, Mikko (IOP Publishing, 2022)

It has been proposed that the negative ion yield of a caesium sputter ion source could be enhanced by promoting neutral caesium atoms to electronically excited 7p states supporting resonant ion pair production. We have ...
The biased disc of an electron cyclotron resonance ion source as a probe of instability-induced electron and ion losses

Tarvainen, O.; Kronholm, R.; Kalvas, T.; Koivisto, H.; Izotov, I.; Skalyga, V.; Toivanen, V.; Maunoury, L. (American Institute of Physics, 2019)

Electron Cyclotron Resonance Ion Source (ECRIS) plasmas are prone to kinetic instabilities resulting in loss of electron and ion confinement. It is demonstrated that the biased disk of an ECRIS can be used as a probe to ...
Characteristic Kα emission of electron cyclotron resonance ion source plasmas

Sakieldien, Moenir (University of Jyväskylä, 2018)

This thesis presents the results of an investigation of the volumetric Kα emission rate/inner shell ionization rate from an Electron Cyclotron Resonance Ion Source (ECRIS) plasma tuned predominantly for high charge state ...
