Two approaches for $H^{-}$ ion production with 245 GHz ion sources / Gobin, R ; Auvray, P ; Bacal, M ; Breton, J ; Delferrière, O ; Harrault, F ; Ivanov, A A ; Svarnas, P ; Tuske, O
Over the last few years, the accelerator community requested the development of improved negative hydrogen ion sources. For spallation sources, like SNS or ESS, pulsed high intensity H/sup negative ion beams of a few tens of milliamperes, with a duty cycle close to 10%, are required. [...]

Review of scaled Penning $H^{-}$ surface plasma source with slit emitters for high duty factor linacs / Sherman, J D ; Ferdinand, R R ; Gobin, R ; Ingalls, W B ; Rouleau, G ; Sidlow, R ; Smith, H V ; Thomason, J
The Penning H/sup -/ surface plasma source (SPS) is used at Rutherford Appleton Laboratory (RAL) to provide required H/sup -/ beams for charge-exchange injection into the 800-MeV proton synchrotron on the ISIS spallation neutron source. The RAL source is based on the first H/sup -/ Penning SPS operated at Los Alamos. [...]

Status report of the Frankfurt $H^{-}$/-Test LEBT including a non- destructive emittance measurement device / Gabor, C (Goethe Univ.) ; Jakob, A (Goethe Univ.) ; Meusel, O (Goethe Univ.) ; Schafer, J (Goethe Univ.) ; Klomp, A (Goethe Univ.) ; Santic, F (Goethe Univ.) ; Pozimski, J (Goethe Univ.) ; Klein, H (Goethe Univ.) ; Ratzinger, U (Goethe Univ.)
For high power proton accelerators like SNS, ESS or the planned neutrino factory (CERN), negative ions are preferred because they offer charge exchange injection into the accumulation rings (non Liouvillian stacking). The low energy beam emittance is a key parameter in order to avoid emittance growth and particle losses in the high-energy sections. [...]

Preliminary design studies of a 100 MeV $H^{-}H^{+}$ LINAC as injector for SNS synchrotron/ADS LINAC / Pande, S A ; Prasad, M K ; Kulkarni, N S ; Hannurkar, P R
It is proposed to construct a spallation neutron source (SNS) at Centre for Advanced Technology (CAT) based on a 1 GeV proton synchrotron with 100 MeV H/sup -/ LINAC as injector. Additionally, the LINAC can form the first 100 MeV part of a 1 GeV proton LINAC to be built in future for accelerator driven system (ADS) applications. [...]

First Results on the Path Towards a Microwave-Assisted H<sup><font size="-1">-</font></sup> Ion Source / Keller, Roderich ; Anderson, David E ; Luft, Peter A ; Monroy, Marco T ; Ratti, Alessandro ; Regis, Mark J ; Syversrud, Donald L ; Wallig, Joseph G ; Welton, Robert
A novel concept for creating intense beams of negative hydrogen ion beams is presented. In this approach, an ECR ion source operating at 2.45 GHz frequency is utilized as a primary plasma generator and coupled to an SNS-type multi-cusp H-

The front-end systems for the Spallation Neutron Source / Keller, R
The front-end systems (FES) of the Spallation Neutron Source (SNS) project are being built by Berkeley Lab and will deliver a 52-mA H /sup -/ ion beam at 2.5 MeV energy to the subsequent drift-tube linac, to be built by Los Alamos National Laboratory. [...]

Proton and Ion Sources for High Intensity Accelerators / Scrivens, R
Future high intensity ion accelerators, including the Spallation Neutron Source (SNS), the European Spallation Source (ESS), the Superconducting Proton Linac (SPL) etc, will require high current and high duty factor sources for protons and negative hydrogen ions. In order to achieve these goals, a comparison of the Electron Cyclotron Resonance, radio-frequency and Penning ion sources, among others, will be made. [...]

Study of charge state enhancement by means of the coupling of a Laser Ion Source to the ECR ion source SERSE / Gammino, S ; Ciavola, G ; Torrisi, L ; Celona, L
The possibility to produce intense ion beams from solid elements, by using a pulsed Laser ion source as the first stage of the superconducting ECR ion source SERSE is discussed in the following. The Laser ion source may be used to produce negative or positive ions and electrons that are injected into the plasma of SERSE. [...]

Picosecond infrared studies of H$^{-}$ local modes in LaF$_{3}$ / Wells, J P R ; Jones, G D ; Bradley, I V ; Pidgeon, C R
Three-beam normalised pump-probe measurements for the Z-localised vibrational mode of H/sup -/ in LaF/sub 3/ yield a 10 K population decay time (T/sub 1/) of 49 ps. The temperature decrease of this T /sub 1/ time is fitted to two-phonon anharmonic decay together with one-phonon absorption to the 351 cm/sup -1/ higher (X, Y)-mode. [...]
