इंग्रजी मध्ये DYNODE म्हणजे काय?
Dynode
डायऑनोड हे व्हॅक्यूम ट्यूबमध्ये इलेक्ट्रोड आहे जे दुय्यम उत्सर्जनाद्वारे इलेक्ट्रॉन गुणक म्हणून कार्य करते. डायऑनोड समाविष्ट करण्यासाठी प्रथम ट्यूब डायनाट्रॉन होती, ज्यामध्ये मॅग्नेट्रॉनचा पूर्वज होता जो एका डायोनॉडचा वापर करतो. फोटोमल्टीप्लियर आणि व्हिडिओ कॅमेरा ट्युब्समध्ये सामान्यतः डिनोडची श्रृंखला असते, प्रत्येकाने आपल्या पूर्ववर्तीपेक्षा अधिक सकारात्मक विद्युत क्षमतेवर. दुय्यम उत्सर्जन प्रत्येक डीएनॉइडच्या पृष्ठभागावर होतो अशी व्यवस्था छायाचित्राशी निगडीत असणा-या लहान वर्तमानपत्रात वाढ करण्यास सक्षम आहे, विशेषत: एक मिलियन रूपाने.
इंग्रजी शब्दकोशातील dynode व्याख्या
शब्दकोशात डिनोडची परिभाषा म्हणजे इलेक्ट्रोड आहे ज्यावर इलेक्ट्रॉनांचे बीम पडणे शक्य आहे, ज्यामुळे जास्त संख्येने इलेक्ट्रॉनांना दुय्यम उत्सर्जनाने सोडले जाते. सिग्नल वाढवण्यासाठी ते फोटॉल्टप्लिअर्समध्ये वापरले जातात.

Mass Spectrometry: Principles and Applications
The discrete dynode electron multiplier is made up of a series of 12 to 20
dynodes that have good secondary emission properties. As shown in Figure 3.2,
these dynodes are held at decreasing negative potentials by a chain of resistors.
