1. 7 4 including some in ADAS101 ADAS209 and ADAS506 Remember that it is safest to remove your defaults directory member for a corrected program and allow ADAS to recreate it Admittedly I usually forget and only realise I have not done so when a program unexpectedly jumps me back to the main menus 1 ADAS401 The program interrogates condensed iso electronic master files of ADAS data format adf10 They fall into two types standard and partial depending whether metastable states are distinquished and treated along with ground states or if only ground states themselves are addressed We call the two cases also the metastable resolved and metastable unresolved pictures Data classes include free electron recombination coefficients ACD electron impact ionisation coefiicients SCD charge exchange recombination coefficients CCD recombination bremsstrahlung power coefficients PRB charge exchange power coefficients PRC low level excitation line power coefficients PLT metatsable cross coupling coefficients XCD and parent metastable cross coupling coefficients QCD All these coefficients are effective coefficients in the generalised collisional radiative sense Note that adf10 files are stored by iso electronic sequence and so a particular file may have data for several members of an iso electronic sequence They are designed to allow interpolation in ion charge along an iso electronic sequence as common z scaled temperatures and densitie2. availability summary window as illustrated below It is important to use this facility since it shows which master files classes sought by the user were not available where default data files were substituted etc Script file selection is made in the conventional manner at e We have found it convenient to group script files in a personal ADAS database under a subdirectory classification scripts405 Also it is possible to bypass contribution function calculation and display by selecting the NULL script 2 3 2 4 You may find it helpful to copy the NULL script from the central ADAS database to your own space Note that scripts apply to particular cases Thus the references to emissivity coefficient data in a script applying to metastable resolved will not in general work for unresolved data indeed will probably crash We have not built much protection against faulty references into script files at the moment More protection may be added if this proves a stumbling point for users You may find it helpful to fetch the test_c script from central ADAS for first trials VJ Class selection and file availability Member Power USER DATA DEFAULT DATA 93 Class Year Element Prefix Filte Type Sdected Availability Used Available ad 93 c Rpartial YES YES no YES sd 83 c Rpartial YES YES no YES ad 93 c Rpartial no no no no pb 983 c Rpartial YES YES no YES pc 983 c Rpartial n
3. match the bundling program ADAS 209 released earlier I think these two programs will make it easier to cross link between the typical astrophysical and fusion applications More data has been added to the central ADAS database In particular Alessandro has generated substantial additional collections of G Te functions of type adf20 needed for the SOHO satellite data analysis These are located as adas adas adf20 Also the adf04 collections have been extended including the following adas adas adf04 copmm li Peter McWhirter s assessment for lithium like ions from the SOHO CDS data review adas adas adf04 clike Brunella Monsignori Fossi s assessment for the carbon like sequence and data for some ions of iron assessed by Helen Mason adas adas adf04 allike allike_hm fe 13 dat adas adas adf04 arlike arlike_hm fe8 dat adas adas adf04 plike plike_hm fe1 1 dat adas adas adf04 silike silike_hm fel2 dat Lorne Horton and I have put up the old Sampson et al data for the hydrogen like sequence as fadas adas adf04 copsm h but we hope to have their modification due to Callaway s review in place shortly The next data release including the above will put in position on all sites at the end of this week H P Summers 5 Dec 1995

6. that a default year must be specified Often the complete set of data classes for a particular year and type are not available and the capability of filling in from a default perhaps less accurate but more complete year is allowed In general the two digit year number is used to provide the main groupings of data Thus 89 is the standard unresolved JET base line data of low precision but fairly complete 93 is metastable resolved data but available only for light elements of primary importance to fusion Some flexibility for subdivision within a year is provided by allowing a two character member prefix eg pj which may be present in the final part of a file name eg 7 facd93r acd93r_pj c dat The distinctions between standard and partial master file types and resolved and unresolved types must be clarified Standard data is stage to stage and has a specific layout Partial data distiguishes metastables and has a different layout Within the partial data layout it is possible simply to have each stage represented only by its ground state and therefore to be similar to standard data However the layout is the partial one We call such data partial but unresolved The usual partial data with metastables present is called resolved This distinction and added flexibility are helpful in iso nuclear master file preparation and archiving Clicking the Display data set availability button at d causes display of a file

14. nov18 95 ADAS Bulletin Two new programs are ready They are the first of the ADAS series 4 ionisation and recombination processing codes ADAS401 allows interrogation of condensed master files adf10 These are datasets of recombination coefficients ionisation coefficients power coefficients etc stored in isoelectronic sequence groups ADAS405 is an equilibrium ionisation balance code capable of working with either unresolved stage to stage or resolved metastables distinguished iso nuclear master file datasets adf11 It is quite sophisticated allowing production and display of generalised contribution functions as well as the more usual fractional abundances and power functions I hope its capabilities will prove helpful These programs are the first of their type and have proved quite time consuming for Tim to convert Meanwhile Alessandro has being working hard on a differential emission measure analysis code and environment it has been set up also to become an ADAS utility The code is quite complex and uses the integral inversion core by Alan Thomson This code is presently under test at Strathclyde University and at Rutherford Appleton Laboratory but without its final ADAS title and menu position decided We can make arrangements for consortium members with special interest in this code to have preliminary access to it It will probably be issued in ADAS release 1 5 A number of errors have been corrected and adjustments made in this release
