  1. Open AUC UpdateCFA & Sednterp San Antonio 2012

  2. Open AUC Hardware

  3. CFA 3 feet Upper optical tracks 5 feet Lower optical tracks

  4. Rotor • Fiber composite • Titanium inserts • 8-hole 60,000 rpm • 6.5 cm center • Uses current cells • In situ temperature measurement • In testing

  5. Electronic interfaces Master clock Synchronizer RAM Source/detector control 14-bit 5 MHz A/D Power supply & stack

  6. CFA Synchronizer • Multiple synchronizing modes • Open collection • Fluorescence • Once in a revolution • HRI, MWA • Many times per revolution • LALS • 0.1o resolution and accuracy • Offset, delay, duration for each revolution • Number of repeats per acquisition event • 1 to infinity • Backgroundcomputer updating Master clock Synchronizer

  7. Power supply Master clock Synchro 15 cm DAC Memory Memory Memory SrcDetCTRL 10 cm 10 cm CFA ‘Stack’ architecture • Up to 15 stacks • Up to 7 boards/stack • Master clock • 8 MHz auto ranging • Synchronizer • 14-bit DAC • 3x1-Mbyte RAM • Source/detector control • Each board knows its address • Address: Optical track, stack, board number, board type • Polled on software start up

  8. μs Data acquisition bus • 48-bit parallel DIO • 11bit address/command • 4-bit “stack” address • 3-bit board address • 4-bit command • 16 bits data out • 16 bits data in

  9. Motion control • Provisions for • Stepping motors • Linear motors • Servo motors • Common interface Linear motor scanner Servo driven optical platform Stepping motor driven monochromator

  10. TGi TGi TGi TGi TGi TGi TGi TGi TG1 TGi TG2 TGi TG3 TG4 CPU CFA motion control Motion control subsystem • Separate computer • Token ring network • Up to 255 trajectory generators • Ramp speed up/down • Event generation • Encoded position • Threaded Optical tracks Master daemon Motion Control

  11. MWA Absorbance optics Scan interval = 10 – 15 seconds 0.06 OD

  12. CFA Software subsystems • Master Daemon- communications/UI • Machine- vacuum, temp control, rpm • Motion control- steppers, servos, linears • μs DIO- clocks, synchros, DACs, memory • ms DIO- address, temp logger, A/D • Optical tracks- sources, detectors • Experiment- setup, protocol • Sednterp2- solutions, calculations System integration

  14. Experiment subsystem • User • Login (optional) • Setup • Rotor, cells, channels, windows, etc. • Samples • Match with channels • Sednterp 2 • Protocol • Which optical systems with which samples • Number of scans, delay, interval • Advanced- optical system characteristics (e.g. gains) • RPM, temperature, wait before starting

  15. CFA software status

  16. Update on SEDnterp 2

  17. Sednterp 2 • Based on Sednterp 1 • Thanks to John Philo • Same calculations • Same logic • Imports existing Sednterp 1 data • Multiple versions • Windows XP  7 • Mac OSs • Linux • Web

  18. What’s new in Sednterp 2 • Uses “daemon” model • SQLite DB • Javascript computations in modules • Rendering engines for desktop & web • Public web version in May • David Hayes’ help file now is a Wiki • PDF version available for “unconnected” computers • Daemon has TCP/IP socket • Allows external programs to use Sednterp 2 • XML commands documented • CFA software will use this

  19. Why use Java script? • No recompilation • New Computations • New Tables of values • New User interfaces • New Graphs • E.g. Concentration unit conversion Download: http://bitcwiki.sr.unh.edu/index.php/Downloads
