1 PURPOSE
This Appendix replaces Appendix No. 1, dated April 20, 1988,
which is declared void.
2 SCOPE OF WORK :
AIT will provide the following services to CCNAA under the ex-
panded scope of the project: fabricate four SINGLE CAVITY RF
SYSTEMS with each system contained in a set of racks including
all intrarack wiring. One system will be modified to operate
in the booster synchrotron, three systems will be modified to
be used in the storage ring. Additionally a set of critical s-
pare modules will be provided. The following lists of drawing
of existing SLAC designs will form the basis of the project :
ONE CAVITY LOW-LEVEL RF SYSTEM :

Tuner Driver Phase Detector Station Phase
Shifter
Gap Voltage Contr. Local Oscillator Fan Out
Servo Amplifier RF Attenuator Phase Lock Am-
plifier
Phase Lock Amplifier Nulling Phase Shifter
Reflected Power Det- Kly.Phse Shif-
ector ter

Arc Detector Amplitude Detector Monitor Phase
Shifter

RF STATION CONTROL SYSTEM:
Nim Chassis Nim Interface Tuner PS
Low-Level PS RF Display RF Station Controller
Aualog Distrib. (IN) Analog Distrib.(OUT) Local Remote Switch
Monitor panel Miscellaneous Parts

ADDITIONAL ITEMS FOR STORAGE RING RF SYSTEM INCLUDING DISTRIB :

Sta. Phase Shifter 2x4 Way Divider 4-way Ddvider
Phase Detector Local Oscillator Local Oscillator
FanOut
Fast Phase Shifter Synchrontron Oscillation Detector
Nim Crate Nim Interface

ADDITIONAL ITEMS FOR BOOSTER SYNCHROTRON ;
Track / Hold Ramp Attenuator Local Oscillator
SPARE LOW-LEVEL RF MODULES :

4 COST OFSERVICES :
The estimated total cost of services under this Appendix is U.
S.$ 789,300.00. A breakdown of the cost is attached. From the
total cost there will be deducted the amount of U.S. $324,350.
00, the amount already made available by CCNAA to AIT pursuant
to Appendix No. 1 to the Agreement. The net cost to CCNAA pur-
suant to the provisions of Appendix No. 2 will, therefore, be
U.S.$464,950.00. Payment for the services' provided under this
Appendix shall be as set forth in Article IV of the Agreement.
5 EFFECTIVE DATE :
This Appendix will become effective upon the date of the last
signature hereafter of the representatives of CCNAA and AIT a-
nd remain in effect for the duration of the Agreement.
