1 ARIES-IFE SYSTEMS Ronald Miller (UCSD) ARIES-IFE Project Meeting UCSD Jan. 10-11, 2002

2 Outline Power-Balance Cases: - Direct Drive (KrF Laser) - Indirect Drive (Heavy Ion) --Close-coupled target --Conventional (full-sized) distributed radiator (New)  Target Fabrication Analogy

3 Power Balance Model Reasonably simple model Solved using iDecide TM COTS - influence diagram set-up -used in deterministic (not MC) mode -workaround for recursion

4 KrF Laser Driver Gain Curve ref. S. Bodner, et al., Madrid (June 2000).  Extended asymptotically beyond 3 MJ (-RLM)

5 KrF Driver (efficiency = 0.07)

6 KrF Driver

7 HI Close-Coupled Target Gain Curve ref. D. Callahan-Miller and M. Tabak, Phys. Plasmas, 7, 5 (May 2000) 2083.  Smaller hohlraum to capsule size ratio.  Higher Gain.

8 HI Driver (efficiency = 0.30) Close –Coupled Target: P E

9 HI Driver (efficiency = 0.30) CC: Recirc. Power Fraction

10 HI Conventional Target (full- sized) distributed radiator Gain Curve ref. D. Callahan-Miller and M. Tabak, Phys. Plasmas, 7, 5 (May 2000) 2083.  W. Meier (2 Nov 2001).  Lower Gain.

11 HI Driver (efficiency = 0.30) Conventional Target: P E

12 HI Driver (efficiency = 0.30) dr: Recirc. Power Fraction

13 Common Assumptions Auxiliary power fraction = 0.05 Thermal conversion efficiency = 0.55 5-Hz rep. rate is scalable to other P E (MWe) Recirculating power fraction does not depend on rep. rate

14 Target Fabrication Analogy  Issues: -Mass production -Automation -Quality Assurance (QA) -Remote handling -Low cost  Are there manufacturing analogies?

15 Possible Analogies Computer chips Ammunition Minting of coins Light bulbs -Corning Ribbon Machine

16 Corning Ribbon Machine for Incandescent Light Bulb Blanks Ref. http://www.asme.org/history/brochures/h081.pdfhttp://www.asme.org/history/brochures/h081.pdf Production rate: 2,000 blanks per minute (33/sec) Exploits properties of glass May only work for homogeneous materials
