ENDF (USA) BROND (Former USSR) JENDL (Japan) JEFF (Europe) WPEC (NEA OECD) UK Nuclear Industry Private Companies: Serco, Studsvik of America, CEA, etc. Academic Nuclear Data mostly for physics Industrial Nuclear Data Codes. Reactors. Databases. Safety. Nuclear Data: Collection, Dissemination and Usage

4. nTOF: Class A International Facility

5. nTOF Recruit Research Fellow (C-NET) Formally join nTOF. Contribute to equipment, target material, join in running experiment shifts and analysis work. Network York, (NNL support for Manchester activities) Support data evaluation effort, dissemination. Interests: initially with neutron capture cross section measurements relevant to current and new generation reactors as identified in NEA High Priority Request List ( 238 U, 241 Am, 243 Am) New proposal to the INTC PAC in Nov 2010: Fission of 240/242 Pu, 245 Cm, 232/234 Th, 238 U, Ratio( 238 U/ 235 U ). Later through consultation.

6. Fission fragment spectrometer “STEFF” (running off-line at Manchester with 252 Cf – later moves to GANIL - NFS)

7. Anode signal After digital filtering Noise < 0.2% ~£250 k already invested Current Mass resolution ~4% Upgrade: increase T by factor 3 Novel Digital Pulse-shape analysis Low-noise energy measurements Z sensitivity ~ 1/40

8. STEFF Upgrade and NFS Programme Increase FF flight path to 3m Maintain solid angle Obtain mass resolution ~ 1% After discussions with NNL, suggest: 238 U, 239 Pu and 237 Np, E n =1-20 MeV.
